Detailed Description
In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
Referring to fig. 1, the transaction link-based flow control method of some embodiments of the present description may include the steps of:
s101, acquiring service transaction requests of application node services in the distributed cluster in real time to form a service transaction request set.
S102, carrying out link aggregation on the business transaction requests in the business transaction request set to form one or more transaction links.
S103, extracting the link characteristic value of the transaction link.
S104, determining the business transaction type to which the transaction link belongs according to the link characteristic value so as to acquire the business volume of each business transaction type in the distributed cluster.
And S105, when the traffic volume of one or more business transaction types meets the flow control triggering condition, performing flow control on the business transaction type in an initial application node in the distributed cluster.
Therefore, in the traffic control method based on the transaction link in the above embodiment, the traffic of each service transaction type in the distributed cluster is monitored in real time based on the link tracking, and when the traffic of one or more service transaction types meets the traffic control trigger condition, the traffic of the service transaction type can be controlled in the initial application node in the distributed cluster, so that the traffic control according to the traffic of a specific service scene is realized, the control range of the traffic control is limited to the service transaction types with high concurrency, and the service transaction types with low concurrency are not involved, so that the normal transaction processing of the service transaction types with low concurrency is not affected.
In some embodiments of the present description, the service transaction request received by the application node may be obtained through an Interceptor (Interceptor) or a Filter (Filter). For example, in an exemplary embodiment, the service transaction request received by the application node may be intercepted by techniques such as byte code organization.
In general, application nodes in a distributed cluster may include front-end servers, back-end servers, databases, and the like. A transaction link comprises a plurality of service call links among a plurality of application nodes; meanwhile, the same application node may also relate to service calling links of a plurality of transaction links, and the specific implementation methods of the services called by each service calling link are generally different. Thus, for each application node, by collecting the service transaction requests received by the respective application nodes in the distributed cluster together to form a service transaction request set, it can be used for subsequent link aggregation. The protocol adopted by the business transaction request can be RPC protocol or http protocol, etc.
Since each business transaction request contains a transaction identifier for uniquely identifying the transaction, the business transaction requests in the business transaction request set can be subjected to link aggregation according to the transaction identifier, so that one or more transaction links can be formed. Specifically, service transaction requests containing the same transaction identifier can be queried from the service transaction request set, and the service transaction requests are arranged according to the calling sequence, so that a transaction link can be formed. In this way, one or more transaction links may ultimately be aggregated from a set of transaction requests.
In an embodiment of the present disclosure, the extracting the link characteristic value of the transaction link may include the following steps:
selecting a transaction link;
extracting a calling characteristic value of each business transaction request in the transaction link; the call feature value may be, for example, a call method.
And arranging the calling characteristic values according to the calling sequence to form the link characteristic value of the transaction link.
For example, in FIG. 2, the A transaction link contains five call feature values A1, A2, A3, A4, and A5; accordingly, the link characteristic value of the A transaction link may be represented by the sequence (A1, A2, A3, A4, and A5). The transaction link B comprises three calling characteristic values of B1, B2 and B3; accordingly, the link characteristic value of the B transaction link may be represented by the sequence (B1, B2, B3). The C transaction link comprises two calling characteristic values of C1 and C2; accordingly, the link characteristic value of the C transaction link may be represented by the sequence (C1, C2).
In an embodiment of the present disclosure, the determining, according to the link characteristic value, a service transaction type to which the transaction link belongs may include the following steps:
selecting a transaction link;
inquiring whether a business transaction type matched with a link characteristic value of the transaction link exists in a preset business transaction type characteristic database;
if the business transaction type matched with the link characteristic value of the transaction link exists, the transaction link is marked as the corresponding business transaction type, and the business volume of the corresponding business transaction type is updated. In some special cases, it may occur that there is no business transaction type matching the transaction link characteristics, which may not be processed.
And the service transaction type characteristic database stores service transaction type characteristic sequences of all service transaction types in the distributed cluster. By analyzing the link characteristics of the historical transaction links of the distributed cluster in advance, the corresponding relationship between each service transaction type and the link characteristics can be obtained, as shown in the following table 1:
TABLE 1
For example, in an exemplary embodiment, the link characteristic value of a selected transaction link is a sequence (C1, C2), and the sequence (C1, C2) is found in table 1 by looking up a table, and the corresponding business transaction type is C transaction; the transaction type for that transaction link may be marked as C transaction.
Based on the identification of the business transaction type to which each transaction link belongs, the business volume of the corresponding business transaction type can be updated in the business transaction volume database. Wherein the traffic volume database maintains traffic volumes of the traffic transaction types within a specified period of time, such as shown in table 2 below.
TABLE 2
When the traffic of one or more service transaction types meets the triggering condition of flow control, the service transaction types can be subjected to flow control in an initial application node in the distributed cluster. For example, the flow control threshold for the a transaction is 300, and when the real-time traffic of the a transaction exceeds 300, the a transaction may be flow controlled. The originating application node may be an application node in the distributed cluster that first receives the service transaction request, for example, a front-end server or the like.
In some embodiments of the present disclosure, the control strategy of the flow control may include, but is not limited to, drainage, flow limiting, and/or fusing, and the like, and may be specifically selected according to actual needs, which is not limited in this disclosure.
In some embodiments of the present disclosure, after determining, according to the link characteristic value, a service transaction type to which the transaction link belongs, a real-time transaction call graph of the distributed cluster is generated according to the service transaction type to which the transaction link belongs, and the real-time transaction call graph is output and displayed in real time. Thus, the real-time transaction calling condition of each business transaction type in the distributed cluster can be more clearly and intuitively checked.
In another embodiment of the present disclosure, after determining the service transaction type to which the transaction link belongs according to the link characteristic value, all transaction links may be further persisted into a transaction link detail database.
Referring to fig. 3, corresponding to the traffic control method based on the transaction link, the embodiment of the present disclosure further provides a traffic control device based on the transaction link, where the device may be configured to obtain, in real time, a service transaction request served by an application node in a distributed cluster, so as to form a service transaction request set; link aggregation is carried out on the business transaction requests in the business transaction request set so as to form one or more transaction links; extracting a link characteristic value of the transaction link; determining the business transaction type to which the transaction link belongs according to the link characteristic value so as to acquire the business volume of each business transaction type in the distributed cluster; and when the traffic volume of one or more business transaction types meets the triggering condition of flow control, performing flow control on the business transaction types in an initial application node in the distributed cluster.
In the traffic control device based on the transaction link in the embodiment of the present disclosure, real-time traffic monitoring of each service transaction type in the distributed cluster is realized based on link tracking, and when one or more service transaction types of traffic meet the traffic control trigger condition, the traffic transaction type can be subjected to traffic control in the starting application node in the distributed cluster, so that traffic control according to the traffic of a specific service scenario is realized, so that the control range of the traffic control is limited to only those service transaction types with high concurrency, but not those service transaction types with low concurrency are not involved, and normal transaction processing of the service transaction types with low concurrency is not affected.
