Description

Method, device, terminal and storage medium for executing service

Technical Field

The present disclosure relates to the field of internet technologies, and in particular, to a method, an apparatus, a terminal, and a storage medium for executing a service.

Background

In a remote direct data access (Remote Direct Memory Access, RDMA) network, multiple terminals may simultaneously cause a server to perform the same service, for example, writing log data in the same log in the server.

And the server determines the execution condition of the target service through the service execution progress mark. Before a plurality of terminals commonly request a server to execute a target service, each terminal sends an acquisition request corresponding to the target service for acquiring a mark updating sequence identifier to the server, and the mark updating sequence identifier is used when the service execution progress mark in the server is updated subsequently. There is a counter in the server, and the counter count value is incremented by 1 each time the server receives an acquisition request. The server responds to the acquisition request sent by each terminal, takes the current count value of the counter as the mark updating sequence identifier distributed to the current terminal, and sends the message carrying the mark updating sequence identifier to the current terminal. Then, the current terminal sends a service execution request corresponding to the target service to the server, and the server responds to the service execution request sent by the current terminal to execute the target service and sends a service execution completion message to the current terminal after the target service is executed. Then, the current terminal needs to send a flag update request carrying a pre-acquired flag update sequence identifier to a server, and the server updates the service execution progress flag according to the sequence indicated by the flag update sequence identifier. In practical application, the time required for the process of sending the acquisition request for acquiring the mark updating sequence identifier to the server and the process of sending the message carrying the mark updating sequence identifier to the corresponding terminal by the server is longer, and the time required for the process of actually executing the target service by the server in response to the service execution request is shorter. This is not acceptable.

In order to solve the above-described problems, the related art proposes the following. And the terminal acquires the current count value of the counter in the bottom layer of the server under the condition that the higher layer of the server does not sense through RDMA atomic operation provided by the RDMA network, and determines the current value of the counter as the mark updating sequence mark. The terminal can still instruct the server to execute the target service through RDMA atomic operation. Because the terminal directly carries out RDMA atomic operation at the bottom layer of the server without being processed by a high layer of the server, the execution efficiency of the RDMA atomic operation is higher, the terminal can further quickly acquire the mark updating sequence mark and instruct the server to execute target service, and the service execution progress mark in the bottom layer of the server can be updated according to the sequence indicated by the acquired mark updating sequence mark. For example, if the terminal A, B, C has indicated and determined that the server has completed executing the target service and the flag update sequence identifier allocated by the terminal A, B, C is sequentially 1, 2, and 3, the terminal a updates the service execution progress flag first, and updates the service execution progress flag from the initial value 1 to 2. Only after the terminal a finishes updating the service execution progress mark, when the terminal B obtains that the current service execution progress mark is 2, the terminal B can update the service execution progress mark, and the service execution progress mark is updated to be 3. Only after the terminal a and the terminal B update the service execution progress mark, when the terminal C obtains that the current service execution progress mark is 3, the terminal C can update the service execution progress mark and update the service execution progress mark to 4. If the terminal with the preceding sequence indicated by the mark updating sequence identifier does not update the service execution progress mark, the terminal with the following sequence indicated by the mark updating sequence identifier always waits, and cannot update the service execution progress mark.

In carrying out the present disclosure, the inventors found that there are at least the following problems:

the high-rise of the server needs to check the current business execution progress mark at certain moments, and the execution condition of the target business is determined through the current business execution progress mark. When any terminal indicating the server to execute the target service has an operation fault, other terminals cannot sense the fault, so that even if other terminals with the sequence indicated by the mark updating sequence identification indicate and determine that the server executes the target service, other terminals with the sequence indicated by the mark updating sequence identification cannot update the service execution progress mark, and further the execution condition of the target service determined by the server high-level through the current service execution progress mark is inconsistent with the actual execution condition.

Disclosure of Invention

In order to overcome the problems in the related art, the present disclosure provides the following technical solutions:

according to a first aspect of an embodiment of the present disclosure, there is provided a method of executing a service, the method including:

instructing the server to execute a target service through a remote direct data access, RDMA, atomic operation;

after the server is determined to finish executing the target service, determining at least one detection time point for acquiring a service execution progress mark from the server according to a preset detection time point determination rule;

And when any detection time point is reached, acquiring the service execution progress mark from the server through RDMA atomic operation, determining the duration of the service execution progress mark which is not updated, and carrying out carry updating on the service execution progress mark through RDMA atomic operation if the duration of the service execution progress mark which is not updated is greater than or equal to a preset duration threshold value.

By the method provided by the embodiment of the disclosure, when any terminal indicating the server to execute the target service has an operation fault, other terminals can acquire the service execution progress mark from the server, determine the duration of the service execution progress mark which is not updated, and if the duration of the service execution progress mark which is not updated is greater than a preset duration threshold, the terminal indicating the server to execute the target service has the operation fault, so that other terminals can automatically update the service execution progress mark. Thus, even if a terminal with operation failure exists, other terminals with the sequence indicated by the mark update sequence identifier can continuously update the service execution progress mark. When the higher layer of the server determines the execution condition of the target service through the current service execution progress mark, the determined execution condition of the target service can be matched with the actual execution condition.

In one possible implementation manner, the target service is a service of writing log data in a target log, and the instructing, through an RDMA atomic operation, the server to execute the target service includes:

acquiring a data writing position corresponding to the target log from a server through RDMA atomic operation, and indicating the server to write log data in the data writing position;

after the server is determined to execute the target service, determining at least one detection time point for acquiring a service execution progress mark from the server according to a preset detection time point determination rule, including:

after determining that the server writes the log data in the data writing position, determining at least one detection time point for obtaining a writing position mark for the server according to a preset detection time point determining rule;

and when any detection time point is reached, acquiring the service execution progress mark from the server through RDMA atomic operation, determining the duration of the service execution progress mark which is not updated, and if the duration of the service execution progress mark which is not updated is greater than or equal to a preset duration threshold value, carrying out carry updating on the service execution progress mark through RDMA atomic operation, wherein the carrying updating comprises the following steps:

And when any detection time point is reached, acquiring the writing position mark from the server through RDMA atomic operation, determining the duration of the acquired writing position mark which is not updated, and carrying out carry updating on the writing position mark through RDMA atomic operation if the duration of the writing position mark which is not updated is greater than or equal to a preset duration threshold value.

In one possible implementation manner, the updating the carry of the progress mark of the service execution by RDMA atomic operation includes:

through RDMA atomic operation, the server is instructed to compare the current service execution progress mark with the time length which is not updated and is greater than or equal to a preset time length threshold value;

if the current service execution progress mark is matched with the service execution progress mark with the duration which is not updated being greater than or equal to a preset duration threshold, the server is instructed to increase the current service execution progress mark by a first preset value through RDMA atomic operation;

if the current service execution progress mark is not matched with the service execution progress mark with the duration which is not updated being greater than or equal to a preset duration threshold, indicating the server to keep the current service execution progress mark unchanged through RDMA atomic operation.

By the method, even when a plurality of terminals find that the business execution progress mark needs to be updated in a carry mode, the progress mark is updated in a carry mode only once, and the situation that different terminals update the business execution progress mark in a carry mode for many times is avoided.

In one possible implementation, before instructing the server to execute the target service, the method further includes:

and acquiring the mark updating sequence mark from the server through RDMA atomic operation.

In one possible implementation manner, after determining that the server finishes executing the target service, determining, according to a preset detection time point determining rule, at least one detection time point for obtaining a service execution progress flag from the server includes:

after determining that the server finishes executing the target service, acquiring a service execution progress mark from a server;

determining a difference between the service execution progress mark and the mark update sequence mark;

and according to the difference value, determining at least one detection time point for acquiring the service execution progress mark from the server.

By the method, the number of times that the terminal acquires the service execution progress mark from the server can be reduced, the working pressure of the server is reduced, and the operation efficiency of the server is improved.

In one possible implementation manner, after the service execution progress flag is acquired from the server, the method further includes:

comparing the service execution progress mark with the mark updating sequence mark;

and if the service execution progress mark is smaller than the mark updating sequence mark by a preset difference value, the server is instructed to increase the service execution progress mark by a second preset value.

and if the service execution progress mark is greater than or equal to the mark updating sequence mark, the method goes to the step of executing the RDMA atomic operation to instruct the server to execute the target service.

Some target terminals found to exceed the preset time threshold value and not instruct the server to carry out carry updating on the business execution progress mark are not necessarily or have operation faults. The target terminal may be that the processor is busy at the time when the server should be instructed to carry out the carry update of the service execution progress flag, and there is no time to instruct the server to carry out the carry update of the service execution progress flag. When the processor of the target terminal is at idle time, the target terminal can acquire the service execution progress mark from the server, and compare the acquired service execution progress mark with the mark updating sequence mark acquired in advance, and because the service execution progress mark is automatically indicated by other terminals to carry out updating on the service execution progress mark by the server, the service execution progress mark acquired by the target terminal can be larger than or equal to the mark updating sequence mark acquired in advance. The target terminal cannot successfully update the service execution progress mark, at this time, the target terminal may re-acquire the mark update sequence mark from the server, re-instruct the server to execute the target service, and repeatedly execute all the processes in the embodiments of the present disclosure until the server can be successfully instructed to execute the target service and the service execution progress mark is successfully updated.

In one possible implementation, the preset duration threshold is a duration required by the server to execute the target service once by a preset multiple.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The embodiment of the disclosure provides a method for executing a service, which can be realized by a terminal and is realized by a plurality of other terminals and servers in a matched manner. The terminal may be a mobile phone, a desktop computer, a notebook computer, etc. Fig. 1 is a schematic structural diagram of a system for executing a service according to an embodiment of the disclosure. In the system, a terminal, a plurality of other terminals, a server may be included. These devices belong to RDMA network devices, and these terminals can operate directly on data in the memory of the server bottom layer without being perceived by the server high layer through RDMA atomic operation (RDMA atomic operation is single-sided operation).

The high-rise of the server needs to check the current business execution progress mark at certain moments, and the execution condition of the target business is determined through the current business execution progress mark. When any terminal indicating the server to execute the target service has an operation fault, the terminal except the terminal cannot sense the fault. If the terminal with the subsequent sequence indicated by the mark updating sequence identifier indicates and determines that the server finishes executing the target service, the terminal with the subsequent sequence indicated by the mark updating sequence identifier needs to update the service execution progress mark so that the determined execution condition of the target service accords with the actual execution condition when the server high-level determines the execution condition of the target service through the current service execution progress mark.

An exemplary embodiment of the present disclosure provides a method for executing a service, as shown in fig. 2, a process flow of the method may include the following steps:

step S210, through RDMA atomic operation, the server is instructed to execute the target service.

In implementations, the terminal may instruct the server bottom layer to execute the target service through RDMA atomic operations, which the server high-level does not perceive during execution of the target service. The target service may be a service of writing log data in the target log, or may be other executable transactions.

Before the terminal needs the server to execute the target service, the terminal can acquire the mark updating sequence identifier from the server through RDMA atomic operation, and after the mark updating sequence identifier is acquired, the terminal can instruct the server to execute the target service. If there are multiple terminals that need to execute the target service by the server at the same time, the multiple terminals may sequentially obtain the identifier of the identifier update sequence from the server through RDMA atom operation, and after the identifier update sequence identifier is obtained, the multiple terminals may simultaneously instruct the server to execute the target service, for example, the multiple terminals include terminal A, B, C, and after the terminal A, B, C sequentially obtains the identifier update sequence identifiers 1, 2, and 3, may simultaneously instruct the server to execute the target service, and the server may concurrently execute the target service indicated by the multiple terminals.

Step S220, after determining that the server finishes executing the target service, determining at least one detection time point for acquiring the service execution progress mark from the server according to a preset detection time point determination rule.

In the implementation, the terminal instructs the server to execute the target service, after determining that the server finishes executing the target service, the terminal needs to query the service execution progress mark in the server, and if the queried service execution progress mark is the same as the mark updating sequence mark acquired by the terminal, it is indicated that the terminal can carry out carry updating on the service execution progress mark. In the above process, the terminal needs to query the service execution progress mark in the server, and the terminal may determine, according to a preset detection time point determining rule, a detection time point when the service execution progress mark is subsequently obtained from the server, and when the detection time point is reached, the terminal may query the service execution progress mark in the server once. The detection time point may be one or a plurality of detection time points.

After determining that the server finishes executing the target service, the terminal can query the service execution progress mark in the server, and determine the detection time point of the service execution progress mark in the next query server based on the queried service execution progress mark. And when the determined detection time point is reached, the terminal can inquire the service execution progress mark in the server again, and the detection time point of the service execution progress mark in the next inquiry server is determined again based on the inquired service execution progress mark. The terminal can repeatedly execute the operations until the queried service execution progress mark is the same as the mark updating sequence mark acquired by the terminal, which indicates that the terminal can update the service execution progress mark in a carry way, and the terminal can stop continuously querying the service execution progress mark in the server.

Step S230, when any detection time point is reached, obtaining a service execution progress mark from a server through RDMA atomic operation, determining the duration of the service execution progress mark which is not updated, and if the duration of the service execution progress mark which is not updated is greater than or equal to a preset duration threshold, carrying out carry update on the service execution progress mark through RDMA atomic operation.

In implementation, the terminal may determine, according to a preset detection time point determining rule, at least one detection time point for acquiring the service execution progress flag from the server, and each time any detection time point is reached, the terminal may acquire the service execution progress flag from the server through RDMA atomic operation. Wherein the RDMA atomic operation may be an RDMA Read operation. The service execution progress flag may be a count value in a counter, and may be represented by a sequence generator, an Identity (ID) generator, a logic clock, a count value of a distributed lock, or the like, in addition to the service execution progress flag which may be represented by the count value of the counter.

After the terminal queries the service execution progress mark in the server each time, the terminal can store the service execution progress mark and record a corresponding detection time point. After the terminal inquires the service execution progress mark in the server again, the currently inquired service execution progress mark can be compared with the previously inquired service execution progress mark, if the currently inquired service execution progress markAnd if the detected time point is consistent with the previously queried service execution progress mark, the terminal can determine the difference between the detected time point of the service execution progress mark which is not updated for the first time and the detected time point of the service execution progress mark which is not updated for the current time, and the difference is used as the duration of the service execution progress mark which is not updated. The terminal can judge whether the duration of the service execution progress mark which is not updated is greater than or equal to a preset duration threshold, if the duration of the service execution progress mark which is not updated is greater than or equal to the preset duration threshold, the terminal indicates that one other terminal among the plurality of terminals has operation faults in the process of indicating the server to execute the target service, and the terminal which detects the faults can automatically update the service execution progress mark through RDMA atomic operation. Wherein the RDMA atomic operation may be RDMA CAS (N _p ，N _p +1) operation, N _p And N _p +1 is the parameter that the operation needs to pass in.

Optionally, the preset duration threshold is a duration required by the server with a preset multiple to execute the target service once.

In implementation, the duration required by the server to execute the target service once is set to be T, where T may also be referred to as a lease time, and the preset duration threshold may be T that is a preset multiple. The preset multiple may be set to 2, and the preset duration threshold may be 2T, i.e., 2 lease times. The preset duration threshold may be set according to actual requirements, or the multiple may be set.

Optionally, before instructing the server to execute the target service, the method provided by the embodiment of the present disclosure may further include: and acquiring the mark updating sequence mark from the server through RDMA atomic operation.

In an implementation, when the target service is a service in which log data is written in the target log, the flag update sequence identifier may be the same value as the data writing location, that is, in what data writing location log data is written, and in what sequence the service execution progress flag is updated.

Optionally, when the target service is a service of writing log data in the target log, the method provided by the embodiment of the disclosure may include: acquiring a data writing position corresponding to a target log from a server through RDMA atomic operation, and indicating the server to write log data in the data writing position; after determining that the server writes log data in the data writing position, determining at least one detection time point for obtaining a writing position mark from the server according to a preset detection time point determining rule; and when any detection time point is reached, acquiring a writing position mark from a server through RDMA atomic operation, determining the duration of the acquired writing position mark which is not updated, and carrying out carry updating on the writing position mark through RDMA atomic operation if the duration of the acquired writing position mark which is not updated is longer than a preset duration threshold value.

In implementation, as shown in fig. 3, a Counter may be provided in the server, which may be referred to as a Counter, and may include two parts, a first part being processing and a second part being Nincoming. The total data amount of the count value of the counter can be 64 bits, the Nprocessing can occupy 32 bits, and the Nincoming can occupy 32 bits. The count value of the processing may represent the sequence number (also referred to as a writing location flag) currently being processed, and the count value of the ninstarting may represent the number (also referred to as a data writing location) that the terminal that next obtains the flag update sequence identification from the server can take. Of course, the total data amount of the count value of the counter may be set to other values, which is not limited to the embodiment of the present disclosure.

The system for executing the service may include a terminal and a Server, where the terminal may be referred to as a Client and the Server may be referred to as a Server. As shown in fig. 4, the Client and the Server are disposed in the RDMA network, and the Client and the Server are respectively installed with an RDMA driver, and the Server is also installed with a Memory (Memory), which is an operation object of an RDMA atomic operation. In practical applications, multiple Client ends and multiple Server ends may be set in the RDMA network, and in the embodiments of the present disclosure, the working mechanisms of one Client end and one Server end are described as an example, and the working mechanisms of other Client ends and other Server ends are similar to those described above, and will not be repeated here.

The Client side can instruct the Server side to execute specific operations through RDMA atomic operations. In the disclosed embodiment, the 3 RDMA atomic operations are mainly involved, including RDMA Fetch-and-Add (N _i ) An operation, which may be denoted as RDMA FAA (N _i ) The method comprises the steps of carrying out a first treatment on the surface of the RDMA Read operations, which may be referred to as RDMA Read; RDMA Fetch-and-Add (N) _p ) Operations, denoted RDMA FAA (N _p )。

When the Client needs to write log data in the Server, as shown in fig. 5, the Client may write log data in the Server through RDMA FAA (N _i ) And (3) acquiring the counted value of Nincoming in the Server terminal, and simultaneously adding 1 to the counted value of Nincoming in the Server terminal. As shown in fig. 6, when the detection time point is reached, the Client may obtain the count value of processing and the count value of Nincoming in the Server through RDMA Read. As shown in FIG. 7, when the count value of Nprocessing queried by the Client is the same as the count value of Nincoming obtained by the Client, it is indicated that the Client can update the Nprocessing in the Server, and the Client can update the Nprocessing in the Server through RDMA FAA (N _p ) The count value of the processing in the Server terminal is obtained, and the count value of the processing in the Server terminal can be increased by 1. When the count value of the Nprocessing queried by the Client is smaller than the count value of the Nincoming acquired by the Client (N is greater than or equal to 1), the Client can record the count value of the Nprocessing queried currently. When reaching the detection time point again, the Client can query the count value of the Nprocessing again, if the queried count value of the Nprocessing is not updated compared with the previously queried count value of the Nprocessing and the updated time length is greater than the preset time length threshold, the Client can determine whether the data is updated by RDMA CAS (N _p ，N _p +1) operation, automatically updating the carry of the business execution progress mark.

Optionally, the step of updating the traffic execution progress marker with carry through RDMA atomic operations may include: through RDMA atomic operation, the instruction server compares the current service execution progress mark with the time length which is not updated and is greater than a preset time length threshold; if the current service execution progress mark is matched with the service execution progress mark with the time length which is not updated and is greater than a preset time length threshold value, the server is instructed to increase the current service execution progress mark by a first preset value through RDMA atomic operation; if the current service execution progress mark is not matched with the service execution progress mark with the time length which is not updated and is greater than the preset time length threshold, the server is instructed to keep the current service execution progress mark unchanged through RDMA atomic operation.

In implementations, the terminal may be configured to communicate with the RDMA CAS (N _p ，N _p +1) operation, automatically updating the carry of the business execution progress mark. Wherein N is _p And N _p +1 is a parameter that needs to be entered for operation, N _p For business execution progress mark needing carry updating, N _p +1 is a business execution progress mark after carry updating, and N can be calculated _p +1 is set to be a ratio of N _p A value of 1. In this way, the terminal may communicate with the RDMA CAS (N _p ，N _p +1) operation, instructing the server to compare the current service execution progress flag with N _p If the current business execution progress mark and N _p The instruction is valid, and the current business execution progress mark can be replaced by N _p +1。

If the terminal finds that the service execution progress mark needs to be updated in carry, other terminals also find that the service execution progress mark needs to be updated in carry through the method provided by the embodiment of the disclosure, and the server may receive the indication of updating the service execution progress mark in carry twice or more. At this time, the server updates the service execution progress flag with carry according to the indication of the first received carry update of the service execution progress flag. After carrying out carry updating on the business execution progress mark, if the instruction of carrying out carry updating on the business execution progress mark is received later, the parameter N carried in the instruction _p The current business execution progress mark is not consistent with the server, so that the instruction indication is invalid, and the server keeps the current business execution progress mark unchanged.

Optionally, after determining that the server finishes executing the target service, according to a preset detection time point determining rule, determining at least one detection time point for obtaining the service execution progress flag from the server may include: after determining that the server finishes executing the target service, acquiring a service execution progress mark from the server; determining a difference between a service execution progress mark and a mark update sequence mark; and determining at least one detection time point for acquiring the service execution progress mark from the server according to the difference value.

In implementation, the terminal may determine at least one detection time point for obtaining the service execution progress flag from the server, where a time interval of each time point is the same and is a preset value. Or, the terminal may acquire the service execution progress flag from the server after determining that the server has completed executing the target service, determine a difference between the service execution progress flag and the flag update sequence flag, and determine at least one detection time point for acquiring the service execution progress flag from the server according to the difference.

After determining that the server finishes executing the target service, the terminal can timely acquire a service execution progress mark from the server for determining the number of the sequence numbers currently being processed, and can also determine a mark update sequence mark acquired in advance for determining the number of the sequence numbers taken by the terminal. When the currently processed sequence number is matched with the sequence number taken by the server, the description turns to instruct the server to update the business execution progress mark. If the current sequence number is different from the sequence number taken by the terminal, the terminal can wait a period of time to acquire the service execution progress mark from the server again. In practical application, the terminal may determine a difference between the service execution progress flag and the flag update sequence flag, and determine a detection time point for acquiring the service execution progress flag from the server according to the difference.

For example, the service execution progress flag is 1, the flag update sequence is identified as 3, and the difference value between the two is 2, which indicates that two terminals need to instruct the server to carry out the update of the service execution progress flag before the current terminal instructs the server to carry out the update of the service execution progress flag. Assuming that the length of time required by the server to execute the target service once is T, the current terminal can wait for the determined T of the multiple of the difference to acquire the service execution progress mark again from the server, namely wait for 2T to acquire the service execution progress mark again from the server. Thus, when the terminal acquires the service execution progress mark again from the server, the acquired service execution progress mark should be identical to or closer to the mark update sequence mark acquired in advance. The detection time point determined based on the difference value may be regarded as a first detection time point, a time point obtained by adding T to the first detection time point may be regarded as a second detection time point, and a time point obtained by adding T to the second detection time point may be regarded as a third detection time point. Similarly, when the first detection time point is determined, a time point obtained by adding T to the first detection time point is taken as one detection time point, and finally a plurality of detection time points can be obtained.

Or, the terminal may determine the first detection time point, and acquire the service execution progress flag from the server after the first detection time point is reached, determine a difference between the service execution progress flag and the flag update sequence flag, and determine, according to the difference, a second detection time point for acquiring the service execution progress flag from the server. The terminal may repeatedly perform the step of acquiring the service execution progress marker from the server when the determined detection time point is reached, determining a difference between the service execution progress marker and the marker update sequence identifier, and determining the detection time point of acquiring the service execution progress marker from the server according to the difference until the service execution progress marker acquired by the terminal is identical to the marker update sequence identifier acquired in advance thereof, and stopping repeatedly performing the above steps.

Optionally, after acquiring the service execution progress flag from the server, the method provided by the embodiment of the present disclosure may further include: comparing the service execution progress mark with the mark updating sequence mark; if the service execution progress mark is matched with the mark updating sequence mark, the server is instructed to increase the service execution progress mark by a second preset value.

In implementation, each time when any detection time point is reached, the terminal may acquire a service execution progress flag from the server, compare the acquired service execution progress flag with a flag update sequence identifier acquired in advance, and instruct the server to update the service execution progress flag by indicating that the service execution progress flag is updated by the terminal if the service execution progress flag is the same as the flag update sequence identifier, where the terminal may instruct the server to increase the service execution progress flag by a second preset value (e.g. 1).

Optionally, after acquiring the service execution progress flag from the server, the method provided by the embodiment of the present disclosure may further include: if the service execution progress flag is greater than or equal to the flag update order flag, then the process proceeds to execute an RDMA atomic operation, instructing the server to execute the target service.

In implementation, some target terminals found to exceed the preset time period threshold value and not instruct the server to carry out updating on the business execution progress mark are not necessarily or have operation faults. The target terminal may be that the processor is busy at the time when the server should be instructed to carry out the carry update of the service execution progress flag, and there is no time to instruct the server to carry out the carry update of the service execution progress flag. When the processor of the target terminal is at idle time, the target terminal can acquire the service execution progress mark from the server, and compare the acquired service execution progress mark with the mark updating sequence mark acquired in advance, and because the service execution progress mark is automatically indicated by other terminals to carry out updating on the service execution progress mark by the server, the service execution progress mark acquired by the target terminal can be larger than or equal to the mark updating sequence mark acquired in advance. The target terminal cannot successfully update the service execution progress mark, at this time, the target terminal may re-acquire the mark update sequence mark from the server, re-instruct the server to execute the target service, and repeatedly execute all the processes in the embodiments of the present disclosure until the server can be successfully instructed to execute the target service and the service execution progress mark is successfully updated.

In an application scenario, when the target service is a service of writing log data in the target log, as shown in fig. 8, there are 3 terminals that need to write log data in the target log at the same time, and these 3 terminals include Client 1, client 2, and Client3. Before each Client writes log data, the Client needs to acquire a data writing position from the server, so that different clients can acquire different data writing positions respectively, and different clients can instruct the server to write log data in parallel. In fig. 8, the Client and the Server interact, as indicated by the serial numbers in brackets in the connection line in fig. 8, the serial numbers indicate the sequence of the interactions from small to large, and the Client and the Server interact 7 times according to the serial numbers, including:

(1) Client 1 via RDMA FAA (N _i ) Operation, obtaining current N from server _i The value 1, the data writing position 1 is acquired.

(2) Client 2 via RDMA FAA (N _i ) Operation, obtaining current N from server _i Value 2, data write location 2 is acquired.

(3) Client3 via RDMA FAA (N _i ) Operation, obtaining current N from server _i Value 3, data write location 3 is acquired.

Note that N is obtained at Client 1, client 2, and Client3 _i After the data writing position, the server may be instructed to write the log data on the acquired data writing position in parallel.

(4) When Client 1 indicates that the server has written log data, client 1 may write the log data via RDMA FAA (N _p ) Operation release N _p Release N _p May also be referred to as commit operation, N in the server _p At this time 2, N _i At this point 3.

(5) Client 1 release N _p Thereafter, if log data is also to be written again, RDMA FAA (N _i ) Operation, obtaining current N from server _i Value 4, data write location 4 is acquired.

(6) Each Client is ready to commit after determining that the server is writing log data. At this time, each Client determining that the server has written log data will obtain the current N from the server _p To determine if it is the current Client's turn to commit. If any of the clients (e.g., client 3 in FIG. 8) finds after 2T, N _p Without an update, the Client can determine that there is an operational failure of the target Client (e.g., client 2 in FIG. 8). At this time, client 3 may pass through RDMA CAS (N _p ，N _p +1) operation, N in the server _p The value of (2) is increased by 1. Optionally, client 3 may also send a message to the server indicating that Client 2 has failed, indicating that server Client 2 has failed. At this time, np in the server is 3, n _i 4.

(7) After Client 3 determines that the server writes log data, it can be written to the log data by RDMA FAA (N _p ) Operation release N _p N in server _p At this time 4, N _i At this point 4.

By the method provided by the embodiment of the disclosure, the method can not only realize the quick acquisition of the mark updating sequence mark from the server through the RDMA atomic operation, but also avoid the problem that the state cannot be perceived because the RDMA atomic operation is a unilateral operation.
