--------------------------------
Comment: was deleted
(was: Changing 32766 to 32767 is too trivial to waste anyone's time on. I'm
closing this issue.)
> Change prefetch size limit for topics from 32766 to 32767
> ---------------------------------------------------------
>
> Key: AMQ-3242
> URL: https://issues.apache.org/jira/browse/AMQ-3242
> Project: ActiveMQ
> Issue Type: Improvement
> Reporter: Robert Liguori
> Priority: Trivial
>
> The default prefetch size limit for topics is noted as 32766;
> http://activemq.apache.org/performance-tuning.html
> The FUSE source documentation
> (http://fusesource.com/docs/broker/5.4/tuning/index.html) states, "Default
> prefetch limit is 32766. The default limit of 32766 is the largest value of a
> short and is the maximum possible value of the prefetch limit.".
> The largest value for a short actually is 32767
> (http://java.sun.com/docs/books/jls/second_edition/html/typesValues.doc.html).
> This is really a trivial issue, but should the default prefetch limit for
> topics be changed from 32766 to 32767 to reflect the actual ceiling?
> And of course, I would recommend changing the automatic setting to 32767,
> when the maximum has been exceeded. The following warning shows the applied
> default of 32766:
> 16:22:40 WARN maximum prefetch limit has been reset from 50000 to 32766
