Justin Bertram updated ARTEMIS-5189:
------------------------------------
Description:
I am currently migrating from Classic Broker to Artemis Broker and I also want
to enable the Failover (Shared-Stored) switch. I have configured Artemis with
Failover (Shared-Store) and during the failover switch, topic consumers loose
events before reconnecting. When using durable consumers this is not happening
so the problem (as expected) is only replicable for non-durable consumers.
The reason for which I want to avoid using durable consumer is the performance
impact on the broker side when there is a big number of messages and consumers
for them. For a live client using Classic Broker I have observed a big impact
and slowness of the broker under high load (thousands of messages with more
than 300 durable consumers). Indeed I am not able to test the same with Artemis
broker as I do not have access to that environment however my expectation is
that the Artemis broker will behave similarly.
Is there a parameter in Artemis broker to make it wait a bit after the switch
before dropping topic message, so that previous active consumers to have time
to reconnect and consume the messages?
Attached the Artemis Brokers Primary/Backup configuration.
