timestamp)

> Key: IGNITE-19886
> URL: https://issues.apache.org/jira/browse/IGNITE-19886
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Priority: Major
> Labels: ignite-3
>
> *Motivation*
> The commit timestamp is generated in a transaction coordinator for a
> particular transaction at the time when the transaction is committed. Any
> other node cannot get the timestamp through API. A client node cannot be the
> transaction coordinator (because the role is server only), but the client has
> to use this timestamp to track observation one.
> *Implementation notes*
> Extend interface of {{InternalTransaction}} with method:
> {code}
> /**
> * Fixes transaction and returns a commit transaction timestamp.
> *
> * @param commit True when the transaction committed, false is rolled back.
> * @return Future with commit timestamp or {@code null} if timestamp is not
> specified for the transaction type.
> */
> CompletableFuture<HybridTinmstamp> finish(boolean commit);
> {code}
> *Definition of done*
> Transaction commit timestamp can be got through API of
> {{InternalTransaction}}.
