-----------------------------------
Summary: Allow location of $ARTEMIS_INSTANCE/tmp location to be
overridden
Key: ARTEMIS-2026
URL: https://issues.apache.org/jira/browse/ARTEMIS-2026
Project: ActiveMQ Artemis
Issue Type: Improvement
Reporter: Keith Wall
Currently Artemis creates the {{tmp}} directory as a child of
{{$ARTEMIS_INSTANCE}}. There is no mechanism to override the location so the
temporary files are written elsewhere in the filesystem.
Whilst Artemis does take steps to delete the temporary files it has created as
it shuts-down, this relies on the JVM's shutdown hooks firing correctly. If
the JVM or container crashes or aborts, temporary files accumulate. Operator
intervention would then be required to manually delete the files, which is
problematic for use-cases where Artemis is deployed as part of service (as for
http://enmasse.io).
It would be desirable to be able to separate the temporary files from the other
files that represent the Broker's state at a filesystem level. This would
allow the user of Artemis to directly the temporary directory at an operating
system defined temporary location that will be cleared no matter what.
