> When ratis is enabled for OM, it is possible that transactions will be
> replayed. Though most of the replays would be caught and ignored, there are
> some scenarios in which a transaction could be replayed.
> For example, Key1 is created and deleted. If Key1 create transaction is
> replayed, there is no way to determine if this is replayed transaction as
> Key1 would not be existing in the DB anymore. Replaying this transaction
> would be ok as the delete Key1 transaction would also be replayed.
> Though in such scenarios replaying transactions is ok, the audit log would
> also have a duplicate entry corresponding to the replayed transaction. To
> distinguish duplicate transactions, we propose adding the transactionLogIndex
> to the audit log for OM operations.
