--------------------------------------
Summary: Session/Event index rollover: implement
sessionId/indexName affinity cache
Key: UNOMI-741
URL: https://issues.apache.org/jira/browse/UNOMI-741
Project: Apache Unomi
Issue Type: Task
Reporter: Kevan Jahanshahi
Following performance tests done on ticket:
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.
