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.
