Subject [jira] [Commented] (AMQ-4062) durableTopicPrefetch attribute in policyEntry in activemq.xml dont take effect
Date Fri, 21 Sep 2012 02:17:07 GMT


liuming commented on AMQ-4062:

I've created a testcase.The PolicyEntry configure the DurableTopicSubscription correctly when
there's nothing for the topic in the Kaha storage.When KahaDB contains some messages for that
topic,Destination and Subscription info will be recovered and ConsumerInfo will be created
in addSubscriptionsForDestination method in TopicRegion class.After that the value of prefetchSize
of the ConsumerInfo is zero.

> There are three methods to configure the prefetchSize of a consumer,per broker,per connection
and per destination.I configured the policyEntry element in activemq.xml and set durableTopicPrefetch="5".Then
a durable topic Consumer connected to the broker ,but the prefetchSize instance variable of
ConsumerInfo object was 100, the default value for durable topic consumer.Some messages of
the topic consumer were stored in the kahaDB.
