---------------------------------------
Labels: ignite3 (was: )
> Scan subscription cancel does not close a server side cursor
> ------------------------------------------------------------
>
> Key: IGNITE-17666
> URL: https://issues.apache.org/jira/browse/IGNITE-17666
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vladislav Pyatkov
> Priority: Major
> Labels: ignite3
>
> After cursor was changed in IGNITE-17309, the cancel operation does not close
> a cursor opened on a remote node. This proposes to close all resources when
> the corresponding transaction commits.
> But it is still worth to close a cursor just after all data scanned or when a
> client invokes a cancel manually. This has no meaning for implicit
> transactions, because the those transactions are closed just after the scan
> complete.
> The server side logic is already implemented, for close a cursor required to
> send a close message through the replication layer. The close message (look
> at {_}ScanCloseReplicaRequest{_}) should be sent after a subscriber is
> received a last one batch of entries or _Subscription#cancel_ is invoked.
