Embodiment three
In order to allow those skilled in the art to be more apparent from technical solution disclosed in the present application, the application is also mentioned
A kind of preferred embodiment is supplied.
The present invention provides a kind of group flows of high-performance High Availabitity to control solution, for applying more piece at one
In the case where point clustering deployment, the control of flow is accurately carried out to the cluster.
First, to introduce cluster flow control solution why.Assuming that having 10 machines in a present cluster, we are given
Every machine setting single machine current limit threshold is 10QPS, and the current limit threshold of ideally entire cluster is just 100QPS.It is but real
Border situation down-off may be uneven to every machine, will lead to certain machines in the case that total amount does not arrive and begins to limit
Stream.Therefore it only goes accurately limit bulk flow if limiting by single machine dimension.And cluster flow control can be controlled accurately
Make the calling total amount of entire cluster.
Second, any problem can be brought after introducing cluster flow control.Now, we specially count certain by a Server
The total calling amount of a application, all nodes of the application are all communicated with this Server to determine whether can call, at this moment, I
Have been found that this Server delay machine, the statistics of entire flow will be unable to carry out, also will be unable to basis using all nodes
The current limliting that total flow carries out node is counted, therefore, we introduce a third party by the Server of more statistics flows of deployment
High-availability cluster monitors the Server cluster of statistics flow, and when there is a Server delay machine failure, third party's cluster can be quick
The variation for learning enabled node in the server cluster of statistics flow, the enabled node after variation is notified to answer to application node
One is found out from enabled node with node, is communicated with this Server to determine whether can be called.
Currently, this concept of micro services is very universal in internet industry, many Internet companies all by itself
Backend application is split as service unit one by one from monomer, at this point, when flow is gradually increased, for example, ticket is robbed in popular concert,
Double ten is first-class, will certainly some or even certain several services be caused with very big request pressure, at this time, we can pass through
Increase service node (server) to share request flow, still, we can not increase node (server) without limitation after all
Carry out resistance to compression, so, it comes into being for the multi-node cluster fluidics of some service.
Currently, existing cluster flow control solution is as follows:
Ali's open source product Sentinel: Token Server concept is introduced, allows some using all nodes and one
Token Server communication, when some node for having request call to apply, which reports QPS to give Token Server, Token
Server decides whether to provide Token to the node according to the cluster flow control rule of configuration whether allow call request
Pass through.But the scheme of separate unit Token Server can not be provided normally after will generating Token Server Single Point of Faliure naturally
The problem of service.
The present invention increases the active and standby of more Token Server nodes and election scheduling branch on the basis of Sentinel
It holds, when a certain Server delay machine, spare Server node can be switched fast, the energy for providing Token is provided application node
Power avoids Single Point of Faliure, ensure that the High Availabitity of Token Server.Meanwhile application partition thought is introduced, guarantee every
The high-performance treatments ability of Token Server.
Existing cluster flow control solution is to sum up have the disadvantage that:
The request flow that one Server statistics application cluster interior joint reports, there are Single Point of Faliures.That is this Server
There is delay machine, will be unable to receive the requests traffic information that application node reports, can not also feed back whether application node can be adjusted
As a result, will be unable to carry out normal current limliting using all nodes.
The present invention supports statistics the active and standby of flow Server to be switched fast by the system for introducing third party's High Availabitity, it is ensured that
After one Server delay machine, service can be provided by cut-in stand-by Server at once, avoid the Single Point of Faliure of Server, guarantee
The High Availabitity of Server.Meanwhile after application partition ideological guarantee introducing Server active and standby more piece dot pattern, single machine Server system
Count high-performance when flow.
The present invention mainly includes registration center, election scheduling and network communication this three parts.The present invention is as open source product
The High Availabitity high performance solution of Sentinel, is under the jurisdiction of the standalone module of Sentinel, and the module is by Sentinel SDK
It relies on and introduces, when access side needs cluster flow control, need to only introduce the relevant SDK of Sentinel.
