[jira] [Created] (IGNITE-20501) Calcite engine. Memory leak in MailboxRegistryImpl#remotes on JOINs

Aleksey Plekhanov created IGNITE-20501:
------------------------------------------

             Summary: Calcite engine. Memory leak in MailboxRegistryImpl#remotes on JOINs
                 Key: IGNITE-20501
                 URL: https://issues.apache.org/jira/browse/IGNITE-20501
             Project: Ignite
          Issue Type: Bug
            Reporter: Aleksey Plekhanov
            Assignee: Aleksey Plekhanov


When JOIN relational operator is executed, downstream of JOIN can be closed if only one side of JOIN is already drained (see last lines of {{MergeJoinNode.InnerJoin#join}}, for example). In this case query can be prematurely closed, and after this, message for another side of join can arrive and register new {{Inbox}} (see {{ExchangeServiceImpl#onMessage(UUID, QueryBatchMessage)}}), that never will be unregistered.
