Description
Technical Field
The invention relates to the technical field of computers, in particular to a sharing method and device of Session objects in distributed clusters.
Background
In order to improve the data processing efficiency and the data processing reliability, a centralized server is improved, and a distributed cluster data processing architecture is provided. The distributed cluster comprises a plurality of application servers, and the Web server sends a data processing request sent by the client to a specific application server in the distributed cluster for processing according to a load balancing strategy.
The Session object Session represents the process of one-time Session between the server and the client, the Session object Session is stored in the server, and different users are distinguished by Session object identification Session identification numbers for each client. Under the default condition, each application server stores a copy of Session object Session data of the application server, if the request of the user is distributed to another application server next time, the previously created Session object Session cannot be obtained, the user must log in again, and the user experience is poor. In order to implement sharing of Session object sessions in a distributed cluster, Session object sessions in a memory are synchronized among multiple application servers in the prior art, so that Session object sessions are kept consistent and transparent to the outside. If one of the application servers fails, the Web server can search other available application servers and distribute requests according to the principle of load balance, and because Session objects Session among the application servers are synchronized, the Session object Session of the user can be ensured not to be lost.
However, in the process of implementing the embodiment of the present invention, the inventor finds that Session object Session replication in the existing sharing method for Session object sessions in a distributed cluster may reduce performance of a distributed system, and particularly, when a larger object is stored in a Session object Session and the object changes faster, performance reduction is more significant. When the number of the application server instances is increased, the number of times of Session object Session replication and the number of Session object Session data in each application server are increased by multiple, so that the horizontal extension of the distributed system is limited. The content of Session object Session in a specific application server is synchronized to other application servers in a broadcast manner, which may cause a network traffic bottleneck. The application server stores a plurality of Session objects, the memory is increased, the garbage recovery burden is increased, and the performance is seriously reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the present invention. As shown in fig. 1, the method of this embodiment uses a Session object Session storage proxy server as an execution subject, and includes:
s11: receiving a Session object Session search request sent by an application server, wherein the Session object Session search request comprises a Session object Session identification number;
it should be noted that, the application server in the embodiment of the present invention receives a Session object Session search request sent by a client, and sends the Session object Session search request to a Session object Session storage Proxy server (Redis-Proxy).
S12: acquiring a fragment value according to the Session identification number of the Session object;
it should be noted that, in the embodiment of the present invention, the Session object Session storage Proxy server (Redis-Proxy) obtains the fragment value according to the Session object Session identification number in the Session object Session search request. Fragmentation refers to the process of splitting a Session object Session data set into multiple Session object Session storage servers (Redis), each Session object Session storage server (Redis) including a subset of Session data corresponding to each Session identification number.
S13: determining a target Session object Session storage server from the Session object Session storage server cluster according to the fragmentation value;
it should be noted that, in the embodiment of the present invention, the Redis-Proxy obtains the fragmentation value according to the Session identification number, so that the corresponding Redis instance can be located, and the Redis instance does not need to be located by attaching the Redis identification number to the Session identification number.
S14: forwarding the Session object Session search request to the target Session object Session storage server;
it should be noted that, the application server in the embodiment of the present invention no longer accesses the Redis by a direct connection manner, but accesses the Redis instance by the Redis-Proxy; Redis-Proxy supports the same command protocol as Redis, and is transparent to the application server.
For example, Session data is limited to 1024 shards, with 0-511 shards stored to Redis1 and 512-1023 shards stored to Redis 2. And the Redis-Proxy calculates a slicing value according to the Session identification number, and then selects a corresponding Redis instance to read or write Session data. The Session identification number generated by the application server does not need to add information such as a Redis identification number.
S15: receiving Session object Session data which is sent by the target Session object Session storage server and corresponds to the Session object Session identification number;
it should be noted that, in the embodiment of the present invention, the Session storage server as the target Session object sends Session data corresponding to the Session identification number to the Session storage Proxy server (Redis-Proxy).
S16: sending the Session object Session data corresponding to the Session object Session identification number to the application server;
it should be noted that the Session storage Proxy server (Redis-Proxy) receives Session data corresponding to the Session identification number and forwards the Session data to the application server.
According to the Session sharing method for the Session object in the distributed cluster, the application servers do not store Session data, and the Session data does not need to be copied among the application servers, so that compared with the prior art, the memory occupation is smaller, and the garbage recycling performance is improved; the number of application server instances and the service capacity are linearly increased, and the horizontal expansion of a distributed system is facilitated; session data only interacts between the application server and the Session object storage server, which is more beneficial to network flow control and avoids flow bottleneck.
In an optional implementation manner of the embodiment of the present invention, the obtaining a fragment value according to the Session identifier includes:
and acquiring a fragment value according to the Session identification number of the Session object by adopting a Hash algorithm.
Further, the determining a target Session object Session storage server from the Session object Session storage server cluster according to the fragmentation value includes:
receiving a fragment value storage server list sent by a registration center server, wherein the fragment value storage server list comprises a corresponding relation between a fragment value and a Session object Session storage server;
and determining a target Session object Session storage server from the Session object Session storage server cluster according to the corresponding relation between the fragment value and the Session object Session storage server.
It should be noted that, instead of static configuration, the Redis and the Redis-Proxy in the embodiment of the present invention dynamically acquire storage services such as etcd/zookeeper (as shown in fig. 2) of the registry server, so as to easily implement horizontal capacity expansion of the Redis and the Redis-Proxy.
In the embodiment of the invention, in the capacity expansion of the Redis, on one hand, the etcd/zookeeper fragment information needs to be updated, and on the other hand, the original data needs to be migrated to the correct Redis.
Taking fig. 2 as an example, the 0-511 fragments are stored in the instance Redis1, and the 512-1023 fragments are stored in the instance Redis2, at this time, the Redis3 is added, and the equilibrium fragments are realized, and the 341 and 511,512 and 680 fragments are migrated to the Redis3 through the management command. And (3) final fragment layout:
| Redis1 | Redis2 | Redis3 |
| 0-340 | 681-1023 | 341-680 |
after the migration is completed [ 341- & gt 680 ], the fragmented data is stored to Redis3, and the subsequent request of the fragmented fragment is forwarded to Redis 3.
In the reduction of Redis in the embodiment of the present invention, contrary to the expansion, as in the above example, the data in segments [ 341- > 680 ] are respectively migrated to Redis1 and Redis2, and finally the Redis3 is removed.
In addition, in the embodiment of the invention, when a master node of Redis goes down, the slave node automatically becomes the master node to provide service.
Fig. 3 is a flowchart illustrating a Session object Session sharing method in a distributed cluster according to another embodiment of the present invention. As shown in fig. 3, the method of the embodiment of the present invention uses an application server as an execution subject, and includes:
s31: receiving a Session object Session search request sent by a client, wherein the Session object Session search request comprises a Session object Session identification number;
s32: selecting a target Session object Session storage proxy server from a Session object Session storage proxy server cluster;
it should be noted that the application server needs to obtain a Redis-Proxy list from storage services such as etcd/zookeeper (as shown in fig. 2) of the registry server, select one Redis-Proxy as a target Session object Session storage Proxy server according to a balancing algorithm or a random algorithm, and send a Redis command to the target Session object Session storage Proxy server.
S33: forwarding the Session object Session search request to the target Session object Session storage proxy server;
s34: and receiving Session object Session data corresponding to the Session object Session identification number returned by the target Session object Session storage proxy server.
According to the Session sharing method for the Session object in the distributed cluster, the application servers do not store Session data, and the Session data does not need to be copied among the application servers, so that compared with the prior art, the memory occupation is smaller, and the garbage recycling performance is improved; the number of application server instances and the service capacity are linearly increased, and the horizontal expansion of a distributed system is facilitated; session data only interacts between the application server and the Session object storage server, which is more beneficial to network flow control and avoids flow bottleneck.
