> During transaction operation, if there is concurrent redundant bucket re-balance is in
progress, the client can miss a subscription event, if its primary queue is hosted on the
node where bucket gets moved from.
> Consider, three node cluster N1, N2 and N3. With:
> - Client C1 connected to node N2.
> - Primary bucket region B1 on N1. And secondary bucket for B1 on N2.
> - A Transaction is started on N2, which creates a entry on B1.
> - When the TX is committed. At the same time the Bucket B1 on N2 is moved to N3.
> - The Tx commit message from N1 is sent to N2. This also includes the subscription message,
satisfying the client C1.
> - On N2, for offheap region, when bucket is not found locally, the exception response
is sent to back to N1 without processing the subscription message.
