I'm trying to understand the default Camel Thread Pool and how the maxQueueSize is used, or more precisely what's it for?
I can't find any documentation on what this really is or how it's used. I understand all the other parameters as they match what I'd expect from the JDK...poolSize is the minimum threads to keep in the pool for new tasks and maxPoolSize is the maximum number of the same. So how does maxQueueSize fit into this? This isn't part of the JDK thread pool so I don't know how Camel uses this. The context of my question is that we have a from sftp route that seems to be getting thread starved. E.g. the thread that polls the sftp connection is slowing/stopping at times when it is busy processing other files that were previously downloaded. We are using the default camel thread pool that I see has only a max of 20 threads yet a maxQueueSize of 1000. That doesn't make any sense to me yet. I would think one would want a much larger pool of threads (as we are processing lots of files) but no queue at all...but not sure on that as I don't understand how the queue is used. -Dave
