In addition, the flow control architecture provided by the embodiment of the application can be applied to a low flow control scene in which the numerical value of the flow control parameter is smaller than the number of servers, and can realize accurate control of flow control.
According to the above flow control architecture, the flow control method provided in the embodiment of the present application is described in detail below with reference to fig. 2.
Fig. 2 is a flowchart illustrating a flow control method according to an embodiment of the present application, where the flow control method may be applied to a flow control management module in the flow control architecture.
As shown in fig. 2, the flow control method may specifically include the following steps:
s110, a target transaction request is received, where the target transaction request may include an identification of the requesting device.
The target transaction request may be a transaction request sent by any requesting device and may include an identification of the requesting device, where the identification of the requesting device may be a character capable of uniquely identifying the requesting device and may include numbers, letters, symbols, and the like.
In one embodiment, the flow control field value in the target transaction request is obtained, resulting in the identification of the requesting device.
S120, obtaining the number of the transaction requests of the requesting device and the total number of the transaction requests allowed by the requesting device from the database, where the number of the transaction requests of the requesting device and the total number of the transaction requests allowed by the requesting device may be pre-loaded into the database from the flow control configuration module.
The number of transaction requests of the requesting device and the total number of transaction requests allowed by the requesting device may be preset numbers of the database based on the flow control configuration module, where the database may be an in-memory database.
As an example, at the time of service start, the configuration information of the requesting device 1, including the total number of transaction requests allowed, i.e. the maximum request number, and the number of current transaction requests of the requesting device 1, i.e. the current request number, are first preconfigured in the memory database from the flow control configuration module for use in subsequent quick query. When the flow control for the requesting device 1 is 3, the initialized data according to the requirement of the requesting device 1 may be: the request device 1: { current request number: 0, maximum number of requests: 3}. Next, the number 0 of transaction requests of the requesting device 1 and the total number 3 of transaction requests allowed by the requesting device 1 are obtained from the memory database.
And S130, under the condition that the number of the transaction requests is smaller than the total number, recording and updating the current transaction request number of the request equipment to be the number of the transaction requests plus one, and acquiring a server initial value from the database.
As an example, after configuring that the number of the current transaction requests of the requesting device 1 is 0 and the total number of the transaction requests allowed by the requesting device 1 is 3 in the database, when receiving the transaction request a, querying the current configuration information in the database, and determining whether the transaction request a is in a flow control range, that is, the total number of the transaction requests allowed 3 — the number of the current transaction requests 0 is 3>0, and if the number of the transaction requests is less than the total number, the transaction request a is determined to pass, and the transaction request a is in the flow control range. Next, a server initial value, which may be-1, for example, pre-configured in the database is obtained for subsequent determination of the server serving the transaction request a. In addition, the number of the current transaction requests is added by 1 and written back to the database as the updated number of the current transaction requests of the requesting device 1.
S140, determining a server identifier for providing service for the target transaction request according to the initial value of the server, and sending the target transaction request to the server corresponding to the server identifier.
The server initial value may be a server index value used to select the calling server, for example, when the server initial value is-1, the server index is stored in the database: -1.
As an example, when a service is started, a server information array is preconfigured in an in-memory database, for example, a cluster includes 12 servers, and the data initialized according to the requirement may be: server information array [ { server 1}, { server 2}, { … 12} ], server subscript: -1. And then, receiving a transaction request A, acquiring a server subscript value-1 from the cluster database when judging that the transaction request A is in the flow control range, determining a server identifier for providing service for the transaction request A according to the server subscript value-1, and sending the transaction request A to a server corresponding to the server identifier.
And S150, sending the excess flow control information to the request equipment under the condition that the number of the transaction requests is larger than or equal to the total number.
The excess flow control information may be feedback information for prompting the requesting device for a transaction request for excess flow control.
As an example, when the flow control is 3 for the requesting device 1, when receiving the transaction request B of the requesting device 1, the current configuration information in the database is queried, and it is determined whether the transaction request B is within the flow control range, that is, the total number of the transaction requests allowed by the requesting device 1 is 3 — the number of the current transaction requests is 3 — 0, and the number of the transaction requests is equal to the total number, then the transaction request B does not pass through, and the information exceeding the flow control is not sent to the requesting device 1 within the flow control range.
In the embodiment of the application, the target transaction requests including the identification of the request device are received, the number of the transaction requests of the request device and the total number of the transaction requests allowed by the request device are obtained from the database, and the number of the transaction requests of the request device and the total number of the transaction requests allowed by the request device are pre-loaded to the database from the flow control configuration module, so that the efficiency of subsequently inquiring the number of the transaction requests is improved. And then, under the condition that the number of the transaction requests is smaller than the total number, recording and updating the current transaction request number of the request equipment to be the number of the transaction requests plus one, acquiring a server initial value from a database, determining a server identifier for providing service for the target transaction request according to the server initial value, and sending the target transaction request to a server corresponding to the server identifier. And in the case that the number of the transaction requests is greater than or equal to the total number, sending the excess flow control information to the request equipment. In the embodiment of the application, the flow control information of the request equipment is configured into the database through unified logic control, cluster sharing is achieved, cluster flow control can be performed on different request equipment, and when each transaction request arrives, the flow control data in the database is updated, so that accurate control of the flow control data is achieved.
In the embodiment of the application, the initial value of the server is obtained from the cluster database, and the server identifier for providing service for the target transaction request is determined according to the initial value of the server, so that the server in the cluster database can be accurately selected for calling, and the accurate control of the server in the cluster is realized.
In some embodiments, the database may comprise a clustered database; s140: determining a server identifier for providing service for the target transaction request according to the server initial value may specifically include:
and determining the remainder of the sum of the initial value of the server and the preset numerical value and the division of the sum and the total number of the servers in the database as the server identification.
The cluster database may be used to store the server cluster, the cluster database may store the server identifier and the initial value of the server, and the preset value may be a value arbitrarily set by the user according to needs, for example, 0 or 1, and is not limited herein.
As an example, the cluster includes 12 servers, and at the time of service startup, the data initialized in the cluster database may be: server information array [ { server 1}, { server 2}, { … 12} ], server subscript: -1. When a transaction request A is received and is judged to be in a flow control range, a server subscript value of-1 is obtained from a cluster database, one server in a server information array is selected to provide service according to the server subscript value, the server subscript is used for calculating to obtain a remainder of 0 (namely the calculated server subscript is 0) by using the server subscript which is equal to (server subscript + 1)% of the total number of the servers, and the server with the subscript value of 0 is called to provide service for the transaction request A.
In the embodiment of the application, the remainder obtained by dividing the sum of the initial value of the server and the preset numerical value by the total number of the servers in the database is calculated and is used as the server identifier, so that the selection of the servers in the cluster can be more accurate, and the calling accuracy of the servers in the cluster is further improved.
In some embodiments, the flow control method may further include:
and storing the remainder as an updated initial value of the server to a cluster database.
As an example, after receiving the transaction request a and calculating the remainder to be 0 by using the server index to be (server index + 1)% of the total number of servers, the calculated index is returned to the server information array of the cluster database, and the server index in the cluster database is updated to be 0, that is, the server information array is [ { server 1}, { server 2}, { … 12} ], the server index: 0.
in the embodiment of the application, the remainder is stored in the cluster database as the updated initial value of the server, so that the server can be conveniently called for the received transaction request in the follow-up process.
