Ignite cache store behaviour

Question

I have persistent cache store When I put data into the cache, I see in logs that datastore put operation can be called on any cluster node

Is it correct behavior? I ask because I expect that put to the datastore should be called on the same node where put into the cache occurred.

Answer 1

Yes, this is correct for ATOMIC caches which update persistence store from primary nodes. TRANSACTIONAL cache, on the other hand, will update from the node that runs the transaction. This way it's possible to maintain underlying DB transaction to maintain full consistency between cache and DB.
