Delete Inactive Destinations
Features > Destination Features > Delete Inactive Destinations
An ‘inactive’ destination is one that has had no messages pending and no consumers connected for some configured period of time.
By default the broker does not check for inactive destinations. This as governed by the default values for the following options:
However, the broker can be configured to purge inactive destinations. To do so requires using specially configured destination policy entries in combination with the broker attribute:
schedulePeriodForDestinationPurge > 0.
<broker xmlns="http://activemq.apache.org/schema/core" schedulePeriodForDestinationPurge="10000"> <destinationPolicy> <policyMap> <policyEntries> <policyEntry queue=">" gcInactiveDestinations="true" inactiveTimoutBeforeGC="30000"/> </policyEntries> </policyMap> </destinationPolicy> </broker>
In this example the broker will check for inactive destinations every
10 seconds, as determined by
schedulePeriodForDestinationPurge="10000". When a destination purge is triggered the broker will delete any queue that has been empty for longer than
inactiveTimoutBeforeGC="30000" milliseconds (default:
60000 milliseconds) and for which
gcInactiveDestinations="true" is set on its corresponding destination policy entry.
When a destination is removed the broker will log a message like:
INFO Queue - TEST.QUEUE Inactive for longer than 30000 ms - removing ...
