----------------------------------------
Summary: Make sure EntryProcessor is always running on a OWNING
partition
Key: IGNITE-3456
URL: https://issues.apache.org/jira/browse/IGNITE-3456
Project: Ignite
Issue Type: Improvement
Components: cache
Reporter: Alexey Goncharuk
Let's say I need to maintain some sort of an aggregate function over a
partition. This aggregate is maintained using an entry processor, and before an
update this entry processor queries this local aggregate.
If an entry processor is applied on a partition with a MOVING state, the state
of the local aggregate is not valid because not all data has been preloaded. If
entry processor is applied on an OWNING partition, the result is guaranteed to
be correct.
Given that we have implemented late affinity assignment when a new node is
assigned primary only when rebalancing is finished, this should be already
maintained. We just need to add tests verifying the partition state in
EntryProcessor.
