I'm currently evaluating ActiveMQ for a financial application. I want to have a separate topic for each stock which means that for all of the markets that we're following, we need close to 500,000 topics. I ran into an OutOfMemoryException when using v5.* after creating about 1,500 topics. ( http://www.nabble.com/java.lang.OutOfMemoryError%3A-unable-to-create-new-native-thread-on-AMQ-5.0-td17005441i20.html#a21079855 detailed here ) The exception does not occur with v4.1.1, but the broker essentially grinds to halt after creating about 50,000 topics.
Before I go too far down this path, is 500,000 topics an unreasonable expectation for ActiveMQ? Are there any configuration tips for this type of usage?
