> Dist TX cache, node C is joining. In previous topology, entry is owned by A (primary) and B (backup). In new topology, primary ownership is transferred to C, B stays backup.
> 1. TX is prepared in old topology and is being committed, when topology changes
> 2. on C (the new owner), the TX info is received and later even the old entry
> 3. C receives the CommitCommand, therefore, it correctly replays the PrepareCommand.
> 4. When the entries are about to be committed, in TxInterceptor the transaction is found to be already completed as it has lower TxID.
> Result: the transaction is not being executed and stale data stay on the node (with my algortihm it eventually led to complete entry loss).
