That is quite a performance increase! ...Hi Jason,<br /><br />That is quite a performance increase! I've been looking at how to use ActiveMQ for a specific use case that it appears will require me to use selectors. This had me concerned, looking at various information out there about performance when using selectors. Out of curiosity, the selectors you are using above are based on message header values, correct? Not looking at a specific value in each message payload using xpath? Also, does activemq give me the ability to add LevelDB logic to the selector itself, my issue is that I need a specific message from the queue where a numeric value is the lowest of all messages currently queued. (ie: like a xpath min() function.<br /><br />Thanks for the great information.Anonymoushttps://www.blogger.com/profile/04899509854561767918noreply@blogger.com
