Description
Technical Field
The embodiment of the application relates to the technical field of data processing, in particular to a data processing method and device, electronic equipment and a computer storage medium.
Background
Currently, QOS (Quality of Service) design is basically implemented by limiting current, i.e., limiting speed, which is simply understood as a funnel with openings at two ends, a large opening at an input side and a small opening at an output side. The output side always outputs at the maximum predictable rate no matter how large the flow rate on the input side is. As shown in fig. 1A, no matter how much the client is stressed, the server can always meet the requirement of stable service quality on the basis of a stably controllable request amount.
Currently, there are two main ways to limit the flow of requests, one is precision rate control. The accurate rate control is generally used for pre-configuring the rate of the traffic to be controlled on the premise of better pre-estimating the system capacity and the service traffic, and the general method is to use a leak Bucket algorithm or a TokenBucket algorithm. Such algorithms are widely used for various types of system speed limits, such as the basic library guava, the web service Nginx, and various language toolkits. However, this approach requires more adaptation work, e.g., different network environments, different server models, possibly different processing rates, and different rate configurations. The other is pressure feedback control. This control is more useful in scenarios where it is desirable to maximize the capacity of the back-end server, and when the server has capacity to handle requests, the requests are accepted, otherwise they are rejected. Due to different deployment environments of the same server, the processing speeds of the servers may have great differences, and a common implementation manner of the method is to allocate a buffer area for the server, where a request first enters the buffer area to be cached, and then a special processing module of the server obtains the request from the buffer area to process the request. When the processing capacity of the processing module reaches an upper limit, the buffer will be filled with the request, thereby starting to reject the request. However, this approach requires additional buffers, which may be complex to implement. Therefore, how to simply and accurately limit the current of the system becomes a technical problem to be solved urgently.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention shall fall within the scope of the protection of the embodiments of the present invention.
The following further describes specific implementation of the embodiments of the present invention with reference to the drawings.
The mythology service is a bottom layer basic module of a flying distributed consistency system, is widely applied to the Alice cloud as a de facto standard of the consistency service in the Alice cloud, supports numerous weight-level cloud products such as ECS, OSS, MaxCommute, TableStore, VPC, Alimail and the like, and also supports core services such as nailing unitization, ant artificial intelligence service platforms and the like in a group. The mythology service provides a typical series of distributed consistency services such as distributed locks, service discovery, metadata storage, etc. As shown in fig. 1B, the connection between the client and the server of the mythology service is session-based, and the client needs to create a session with the server and maintain the lifetime of the session between the client and the server through periodic heartbeat. The specific process is that the client firstly creates a long connection with the server of the mythology service, then creates a session on the long connection, the session creation is completed, and then a normal request can be sent, and at the same time, a heartbeat renewal session is sent periodically (the session is kept valid), but in the scene of session disconnection, the long connection needs to be created again, and the session is tried to be continued. The server may be a distributed consistency system, which is a distributed consistency system implemented based on a consistency protocol (e.g., Paxos, Raft, etc.). When the coherency protocol is Raft, the system may include a leader node and a plurality of follower nodes. In order to effectively ensure the service quality of the distributed consistency system in a normal scene, the flow limitation needs to be performed on the request sent by the client to the distributed consistency system. Currently, there are two main ways to limit the flow of requests, one is precision rate control and the other is pressure feedback control. However, both of these approaches to limiting requests are too complex and do not provide for fine or precise limiting of requests. Therefore, the data processing method provided by the embodiment of the application can simply, conveniently and accurately limit the current of the request of the distributed consistency system, so that the service quality of the distributed consistency system is effectively guaranteed. The method can be applied to ZooKeeper of the Apache community, web services nginx, and toolkits of various languages, such as ratelimit, a Guava current limiting tool. The specific implementation manner of the data processing method provided by the embodiment of the application is as follows:
referring to fig. 1C, a flowchart illustrating steps of a data processing method according to a first embodiment of the present application is shown.
Specifically, the data processing method of the present embodiment includes the following steps:
in step S101, when it is determined that the distributed consistency system is in a busy state based on the number of data requests to be processed in the distributed consistency system, resource consumption data of the data requests to be processed in the distributed consistency system is estimated.
In this embodiment, the data request to be processed may be a service data request sent by a client to a distributed consistency system. When the number of data requests to be processed in the distributed consistency system reaches a certain number, it may be determined that the distributed consistency system is in a busy state. Specifically, if it is determined that the number of the data requests to be processed is greater than or equal to a preset number threshold, it is determined that the distributed consistency system is in a busy state. The preset number threshold may be set by a person skilled in the art according to actual needs, and the embodiment of the present application is not limited in any way. More specifically, as shown in fig. 1D, it can be considered that a data request sent by a tenant a or a tenant B to a distributed coherency system through a client may form a queue of data requests to be processed after entering the system, only the length of the queue needs to be concerned, which means that only one global value needs to be maintained, one is added when the data request enters the queue, and one is subtracted when the distributed coherency system sends a response to the data request to the client, which may reflect the current operating state of the distributed coherency system, if the global value is too large, which means that the current system has an excessive number of data requests to be processed, the data request sent by the client to the distributed coherency system needs to be limited, which is a characteristic that the existing precise rate control method does not have, and the simple precise rate control only forcibly sets the inflow rate of the data request according to the configured rate, the busyness of the current distributed coherency system is not a concern. Furthermore, the resource consumption data may be understood as resource consumption data estimated when the distributed coherency system processes the pending data request. Specifically, the resource consumption data may be time resource data, calculation resource data, or storage resource data consumed by the distributed consistency system when processing the data request to be processed. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In some optional embodiments, when resource consumption data of the to-be-processed data request in the distributed consistency system is estimated, determining a request type to which the to-be-processed data request belongs; determining resource consumption weight data corresponding to the data request to be processed based on the request type to which the data request to be processed belongs; and estimating resource consumption data of the data request to be processed in the distributed consistency system based on the resource consumption weight data corresponding to the data request to be processed. Therefore, the resource consumption data of the data request to be processed in the distributed consistency system can be accurately estimated by determining the request type to which the data request to be processed belongs and the resource consumption weight data corresponding to the data request to be processed. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In one specific example, the request type to which the pending data request belongs may include at least one of: read request, list request, create request, update request, delete request, heartbeat, session create request, session continue request. Wherein the list request can be understood as a request for requesting a list or a manifest. Before resource consumption data of the data request to be processed in the distributed consistency system is estimated, request types and resource consumption weight data corresponding to each request type can be configured in advance. For example, when the request type is a read request, the resource consumption weight data corresponding to the read request may be 2, when the request type is a list request, the resource consumption weight data corresponding to the list request may be 4, when the request type is a create request, the resource consumption weight data corresponding to the create request may be 3, when the request type is an update request, the resource consumption weight data corresponding to the update request may be 3, when the request type is a delete request, the resource consumption weight data corresponding to the delete request may be 3, when the request type is a heartbeat, the resource consumption weight data corresponding to the heartbeat may be 1, and when the request type is a session creation request, the resource consumption weight data corresponding to the session creation request may be 3, when the request type is a session renewal request, the resource consumption weight data corresponding to the session renewal request may be 1. The resource consumption weight data can be understood as data for measuring resources consumed by the distributed consistency system when the distributed consistency system processes the request of the request type, and the resource consumption weight data can be set according to different characteristics of each system. In addition, the request types may not be limited to the above request types, and may be extended to other possible request types. When determining the request type to which the data request to be processed belongs, the request type to which the data request to be processed belongs may be determined according to the content of a request header in the data request to be processed or a type field in a request carrier. When determining the resource consumption weight data corresponding to the data request to be processed, the corresponding relationship between the pre-configured request type and the resource consumption weight data can be searched according to the request type to which the data request to be processed belongs, so as to determine the resource consumption weight data corresponding to the data request to be processed. When the resource consumption data of the data request to be processed in the distributed consistency system is estimated, the resource consumption weight data corresponding to the data request to be processed can be accumulated to obtain the resource consumption data of the data request to be processed in the distributed consistency system. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In a specific example, the number of pending data requests in the distributed coherency system cannot completely reflect the busy level of the current system, because different data requests cause different resource consumptions of the system, for example, the resource consumption caused by reading one node and the system resource consumption caused by reading multiple nodes are different, and the resource consumption caused by reading requests and writing requests are different, so that a resource consumption weight is configured for each request type, a virtual processing counting mode for the data requests is formed, so that a separate processing count does not need to be set for each request, a global resource consumption data can be set for the distributed coherency system, and the system is considered to be stably controllable as long as the resource consumption of the pending data requests in the current system is kept within a reasonable range, once overridden, a throttling operation needs to be performed on data requests sent by the client to the system. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In step S102, when it is determined that the resource consumption data exceeds the global resource consumption permission data set by the distributed consistency system, a current limiting operation is performed on a data request sent by a client connected to the distributed consistency system.
In this embodiment, if the resource consumption data of the data request to be processed in the distributed consistency system is less than or equal to the global resource consumption permission data set by the distributed consistency system, it is indicated that the distributed consistency system is stable and controllable, and it is not necessary to perform a current limiting operation on the data request sent by the client to the distributed consistency system. And if the resource consumption data of the data request to be processed in the distributed consistency system is larger than the global resource consumption allowable data set by the distributed consistency system, performing current limiting operation on the data request sent by the client to the distributed consistency system. Specifically, by closing the session between the client and the distributed consistency system, or stopping monitoring the long connection for creating the session, it is possible to implement the current limiting operation on the data request sent by the client to the distributed consistency system. The global resource consumption permission data may be set by a person skilled in the art according to actual needs, and this is not limited in this embodiment of the present application. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
According to the data processing method provided by the embodiment of the application, when the distributed consistency system is determined to be in a busy state based on the number of data requests to be processed in the distributed consistency system, resource consumption data of the data requests to be processed in the distributed consistency system are estimated; when the resource consumption data exceed the global resource consumption allowable data set by the distributed consistency system, performing current limiting operation on data requests sent by a client connected with the distributed consistency system, and compared with the existing other modes, determining whether the distributed consistency system is in a busy state according to the number of data requests to be processed in the distributed consistency system, and estimating the resource consumption data of the data requests to be processed in the distributed consistency system when determining that the distributed consistency system is in the busy state based on the number of the data requests to be processed in the distributed consistency system; when the resource consumption data is determined to exceed the global resource consumption allowable data set by the distributed consistency system, the current limiting operation is performed on the data request sent by the client connected with the distributed consistency system, the current limitation can be simply, conveniently and accurately performed on the request of the distributed consistency system, and therefore the service quality of the distributed consistency system is effectively guaranteed.
The data processing method of the present embodiment may be performed by any suitable device having data processing capabilities, including but not limited to: cameras, terminals, mobile terminals, PCs, servers, in-vehicle devices, entertainment devices, advertising devices, Personal Digital Assistants (PDAs), tablet computers, notebook computers, handheld game consoles, smart glasses, smart watches, wearable devices, virtual display devices or display enhancement devices (such as Google Glass, Oculus rise, Hololens, Gear VR), and the like.
Referring to fig. 2, a flowchart illustrating steps of a data processing method according to a second embodiment of the present application is shown.
Specifically, the data processing method of the present embodiment includes the following steps:
in step S201, a session creation request with tenant information sent by the client is received.
In this embodiment, a tenant field may be added to a request header or a request bearer of the session creation request, and tenant information is carried by the tenant field. The tenant information may include at least one of: the tenant name, the tenant identification information and the tenant validity information. The tenant information is transmitted to the distributed consistency system through the session creation request, the independent control of the service is mainly realized, and different priorities can be provided for services with different importance according to the degradation principle, so that the important service request can be guaranteed to be processed in time under the abnormal condition. In addition, the distributed consistency system can perform richer current limiting work according to different tenants. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In step S202, based on the session creation request, a session corresponding to the tenant information is created, so as to receive, through the session, the pending data request sent by the tenant through the client.
In this embodiment, the session may be understood as a mechanism in which the client creates a lease with the distributed consistency system and needs to periodically send a heartbeat to the distributed consistency system to maintain the lease for a long time. The lease is understood to be a time period occupied by a certain resource in the computer field. If the lease is not extended before the deadline, the resource will be automatically released from its occupation. In addition, a plurality of users often use the system, different users refer to different tenants, and in the system, the data or requests of different tenants are often isolated and do not affect each other. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In a specific example, since the system is a session-based distributed consistency system, the tenant and the session can be bound only by adding tenant information to the session creation request, without requiring the tenant information to be transmitted to each data request. Once the session is established, all data requests in the session process are bound on one tenant, and the design simplifies the complexity of the system and reduces the data volume transmitted by the network. Of course, when the tenant information is transferred, each data request may also carry the tenant information, which increases the burden of network transmission, but is applicable to a scenario in which information of multiple tenants is stored in a single session. Such a scenario may occur in a front-end of a distributed consistency system, where the front-end proxies service requests of different tenants and completes service requests of different tenants in one session. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In step S203, when it is determined that the distributed consistency system is in a busy state based on the number of the to-be-processed data requests in the distributed consistency system, resource consumption data of the to-be-processed data requests in the distributed consistency system is estimated.
Since step S203 is similar to step S101, it is not described herein again.
In step S204, when it is determined that the resource consumption data exceeds the global resource consumption permission data set by the distributed consistency system, a current limiting operation is performed on the data request sent by the client.
Since step S204 is similar to step S102, it is not repeated herein.
In some optional embodiments, the method further comprises: determining the type of a tenant to which the data request to be processed belongs; and based on the type of the tenant, performing a current limiting operation on a data request sent by the tenant to the distributed consistency system through the client. Therefore, the current limiting operation is performed on the data request sent by the tenant to the distributed consistency system through the client according to the type of the tenant, and the current limiting operation can be performed on the data request sent by the client to the distributed consistency system more finely. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In a specific example, when determining the type of the tenant to which the data request to be processed belongs, the type of the tenant to which the data request to be processed belongs may be determined through the session in which the data request to be processed belongs. Since the session and the tenant information have a corresponding relationship, as long as the session where the data request to be processed is located is determined, the type of the tenant to which the data request to be processed belongs can be determined. Wherein the type of the tenant comprises a normal type and/or an unrestricted type. The tenants are divided into two types, because tenants of some core applications need to have the right of preferentially processing service requests, and in some extreme cases, the tenants need to be preferentially recovered, for example, a front-end machine of a distributed consistency system needs to be preferentially recovered, which can help a back-end system to bear pressure in advance, and in extreme cases, service requests of non-limited type tenants can greatly occupy service request space of normal type tenants, so that the highest-priority processing is obtained. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In a specific example, when the current limiting operation is performed on the data request sent by the tenant to the distributed consistency system through the client based on the type of the tenant, when the type of the tenant is a normal type, if the resource consumption data of the data request sent by the tenant to the distributed consistency system through the client in the distributed consistency system exceeds the resource consumption permission data set by the distributed consistency system for the tenant of the normal type, the current limiting operation is performed on the data request sent by the tenant to the distributed consistency system through the client, or when the data request sent by the tenant through the client is received by the distributed consistency system, if the resource consumption data of the data request to be processed in the distributed consistency system exceeds the global resource consumption permission data set by the distributed consistency system If so, performing a current limiting operation on a data request sent by the tenant to the distributed consistency system through the client; when the type of the tenant is an unrestricted type, if the resource consumption data of the data request sent by the tenant to the distributed consistency system through the client in the distributed consistency system exceeds the resource consumption permission data set by the distributed consistency system for the tenant of the unrestricted type, performing a current limiting operation on the data request sent by the tenant to the distributed consistency system through the client. The resource consumption permission data set by the distributed consistency system for the normal type of tenant and the resource consumption permission data set by the distributed consistency system for the unrestricted type of tenant may be set by those skilled in the art according to actual needs, which is not limited in this embodiment of the present application. In addition, the type of the tenant is not limited to a normal type and/or an unrestricted type, the type of the tenant can be expanded to more types, and meanwhile, the distributed consistency system sets different resource consumption permission data for different types of tenants. It should be understood that the above description is only exemplary, and the embodiments of the present application are not limited in this respect.
In the session disconnection scene, the session cannot be recovered for a long time, basically because of a large number of invalid connections and invalid reconnection requests. When the client is reconnected with the distributed consistency system, a timeout mechanism exists, if the client is reconnected with the distributed consistency system, other service machines can be connected, but the original machine cannot immediately sense the session disconnection event of the client, and can sense the event only after the service data request in the TCP connection is processed, so that a large number of invalid reconnection requests are caused, the subsequent valid reconnection requests cannot be processed in time and become invalid reconnection requests, and the session cannot be recovered between the client and the distributed consistency system for a long time. However, after the data processing scheme provided by the embodiment of the application is adopted, the data requests sent by the client to the distributed consistency system can be simply and finely limited, so that the distributed consistency system is ensured to process effective data requests to the maximum extent, and then disconnected sessions can be quickly recovered. For example, a session of a front-end machine with a distributed consistency system may be quickly restored. Specifically, by setting the tenant of the front-end to be of an unrestricted type, the session of the front-end and the distributed consistency system is preferentially restored. Then, a specific recovery time can be calculated. Assuming that the speed of the distributed consistency system processing per second is V, the total number of sessions in the distributed consistency system is N, and the theoretical recovery time of a disconnected session is:
meaning that if the total number of sessions in the distributed coherency system is 10 ten thousand sessions and the processing speed per second is 2 ten thousand sessions, a recovery of a disconnected session can be done in 5 seconds theoretically.
