static variable in JIRA cluster

[Subhajit Bhuiya]

Our plugin has a static LRU Cache. Will it cause a problem in clustered environment.

If Jira guarantee session affinity -> like request from user1 will always go to node1 or request from user2 will go always to node2 in same session, then we are fine. Else we will have to store this static variable in shared memory so that every node can have accees to it. Does Jira provide such concept of shared memory or anything of such type for static variables in clustered enviroment.
