Subject Re: How to configure 5.3 broker over KahaDB to support lots of unconsumed persistent msgs?
Date Fri, 12 Feb 2010 21:07:10 GMT

For this configuration - flow control will quick in when the disk limit is
reached for the temporary store used to store offline non-persistent
messages - or persistent topic messages with no durable consumers.
For persistent messages - or topics with durable consumers - then it will be
the store limit that will need to be reached before flow control kicks in.
