> Key: UNOMI-741
> URL: https://issues.apache.org/jira/browse/UNOMI-741
> Project: Apache Unomi
> Issue Type: Task
> Reporter: Kevan Jahanshahi
> Priority: Major
> Fix For: unomi-2.2.0
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Following performance tests done on ticket:
> https://issues.apache.org/jira/browse/UNOMI-725
> We need to implement sessionId/indexName affinity cache to speed up access to
> current user session on context requests.
> Due to the nature of the splitted indices for the sessions it's not possible
> to know where exactly is stored the sessionId from the context request.
> We can do a query like it is right now but as shown in the performances
> results test this is impact a lot the performance for concurrent context
> requests.
> So we need to implement a sessionId/indexName affinity cache in the
> persistence service to speed up the loading of current user sessions.
> consider a cache system with a time-to-idle feature that will automatically
> clean the unused sessionId after 30min and make this configurable.
> PoC PR: [https://github.com/apache/unomi/pull/576]
