Liviu Citu updated ARTEMIS-5189:
--------------------------------
    Description: 
Hi,

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 however we would like to use 
non-durable consumers as there is a high workload on the broker (a lot of 
consumers/producers) and it will slow down significantly the message processing 
on the broker side.

Actually initially we were using durable consumers but we have to remove them 
because of performance impact.

Is there a parameter in Artemis broker and/or client 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?

Thank you,

Liviu
