> Key: IGNITE-10695
> URL: https://issues.apache.org/jira/browse/IGNITE-10695
> Project: Ignite
> Issue Type: Bug
> Components: mvcc
> Affects Versions: 2.7
> Reporter: Andrew Mashenkov
> Assignee: Andrew Mashenkov
> Priority: Critical
> Fix For: 2.8
>
>
> Operation like putIfAbsent and replace now tries to transfer Predicate
> instance (filter) to remote node.
> # Almost all filters can't be serialized as they do not have assigned direct
> type.
> # Seems, we have no enough tests and we miss remote-call case for such
> operations.
> # Predicate should be transferred only for "replace" operation if certain
> entry provided, otherwise we should send a correct operation code and use
> corresponding static filter on remote side.
> # This change will break protocol compatibility. Should we bother about it?
> Let's fix protocol and add tests.
