> Time Spent: 20m
> Remaining Estimate: 0h

> h3. Motivation
> On the one hand according to [~vpyatkov] updating txnstate within RO flow
> brings us 20% performance drop, on the other hand RO transaction updates
> corresponding state only for testing purposes, precisely in order to check
> whether transaction rollback was called. See
> org.apache.ignite.internal.tx.TxManager#pending for more details.
> h3. Definition of Done
> * Eliminate txnState local map updates within RO txn flow.
> * Implement different mechanism for txn cleanup verification instead of
> txnState local map based one.
