------------------------------------------
Summary: Handle unacknowledge messages queue overflow
Key: IGNITE-21370
URL: https://issues.apache.org/jira/browse/IGNITE-21370
Project: Ignite
Issue Type: Improvement
Reporter: Roman Puchkovskiy
Fix For: 3.0.0-beta2
An unacknowledges messages queue contained in RecoveryDescriptor is bounded.
Right now, its overflow (that causes an exception to be thrown) is not handled.
When the queue becomes full, we could forcibly close the cnannel to force
reconnection and unacked messages being resent during a handshake. We need to
be careful with message ordering wrt the message that causes the message queue
to be full. It seems that we need to detect 'the queue has JUST become full,
after adding this message', and not 'we cannot add this message because the
queue is full' as in the latter case it would be difficult to guarantee the
ordering (as the message is not added to the queue).
Also, currently max queue size is 10. A better default should be chosen, and
this must be made configurable.
