Hi,

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.

Thanks,

Rahul.
