Dennis Reed commented on ISPN-4291:
-----------------------------------
Yeah, there may still be room for optimization here.
Two use cases:
- node joining the cluster
It cannot be skipped here, as there may be stale data in the cache store which can only
be determined by looking through it all.
(this was the main use case I was looking at).
- later state transfers
Here it could be skipped if no segments are lost (I.E. repl)
Poor REPL state transfer performance with cache stores
------------------------------------------------------
Key: ISPN-4291
URL: https://issues.jboss.org/browse/ISPN-4291
Project: Infinispan
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: State Transfer
Affects Versions: 6.0.2.Final
Reporter: Dennis Reed
Assignee: Dan Berindei
During a state transfer every single key is loaded from the cache store to determine
whether it's still owned by the local node.
This is an extremely slow operation, and doesn't even make sense for a REPL cache.
