----------------------------------------
Summary: Queue Draining on Graceful Shutdowns
Key: IGNITE-10872
URL: https://issues.apache.org/jira/browse/IGNITE-10872
Project: Ignite
Issue Type: Improvement
Components: general
Reporter: Gabriel Jimenez
Our *issue to solve* was to have the grid complete any waiting and currently
executing tasks on any termination where the signal was not KILL. With current
behavior our tenants were losing data to corruption or incomplete requests due
to job/task interruption on shutdown.
Part of the functionality we were looking for is already exposed in the sense
that the kill/stop functions within org.apache.ignite.Ignition already have the
'cancel' flag parameter. However this flag is hardcoded as 'true' in
org.apache.ignite.internal.IgnitionEx's default shutdown hook (meaning
jobs/tasks will be interrupted). Currently we have changed IgnitionEx's
implementation to depend on an ignite system variable, and set default behavior
to drain on termination with any signal other than KILL. Additional Questions:
Was there an existing solution/approach to our '*issue to solve*' that did not
involved changing the codebase?
Is there another preferred solution for our issue to solve?
