Subject Increasing Duplicate ID Cache size
Date Fri, 07 Jul 2017 11:13:35 GMT

Due to the requirement of being able to store a large number of messages 
in the queue without duplicates, I am considering increasing the 
duplicate id cache size (parameter: id-cache-size) from its default 
value of 2000 to a million. While I know that this would require 
additional memory, I am not sure of what other complications could I run 
into. I have looked up the forums but couldn't find any information 
about increasing the duplicate id cache size.

Is it ok to increase the duplicate id cache size or could it have some 
serious performance implications on ActiveMQ broker? Kindly advise.
