Automatic delete of expired messages
Hi
I don't use persistance, I don't use transaction, I don't use
CLIENT_ACKNOWLEDGE, only automatic aknowledge.
I just saw in some JIRA recent exchanges that there seems to be an official
trick that automatically delete expired messages when there is no consumer
for a queue or a topic.
Can someone explain me the "official" way to do this, and the ActiveMQ
configuration to define ?
Is the number of consumers for a destination (that can be found by analyzing
Adivisory Messages) increased when this trick is used ?
Thank you in advance
Eric-AWL

Today, I don't use persistent messages at all, and just want to release
memory resources when messages are no longer valid.
Do you confirm me that the number of consumers (0 here), that is found into
Advisory messages, is not changed by this automatic behaviour ? It's
important for us to know the exact number of accessible consumers.

You might also want to look into the DiscardingDLQBroker plugin.

With AMQ 5.3, non-persistent messages that expire are automatically
removed/deleted from their destination. Persistent messages are moved to the
DLQ.
By default, the destination sweeps occur every 30 seconds. You can change
this default via the 'expireMessagesPeriod' property.
