> Fix partition counter reservation.
> ----------------------------------

> Key: IGNITE-17123
> URL: https://issues.apache.org/jira/browse/IGNITE-17123
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Reporter: Andrey Mashenkov
> Assignee: Andrey Mashenkov
> Priority: Major
>
> Transaction reserves partition counters on primary.
> On the backup side, TxEntries must be commited with counters from the
> reserved range.
> However, a range of update counters, which were reserved on primary, is NOT
> validated on backup. Thus means NOOP invoke operation may cause partition
> counter difference on the primary and backup nodes.
> 1. Let's pass NOOP result of invoke operation to the backup and avoid
> incorrect partition counter change on backup nodes (see DhtTxPrepareFuture).
> 2. Update counter can be assigned to TxEntry instantly on tx commit on Remote
> node (for the WAL purposes) instead of allocate+iterate over
> new collection (GridDistributedTxRemoteAdapter.commitIfLocked).
