[jira] [Commented] (CAMEL-9460) RabbitMQ - Wonder if the consumer can use a grown/shrink thread pool

["Preben Asmussen (JIRA)" <ji...@apache.org>]

Preben Asmussen commented on CAMEL-9460:
----------------------------------------

Here is a proposed patch https://github.com/pax95/camel/commit/56c5ba20e768883db75e68092603c7449be1d191 
To me it seems reasonable that the threadpool is allocated = the number of concurrent consumers(open channels), but since I'm not a Rabbit user myself, maybe a Rabbit user has some comments.

Btw I have removed the threadPoolSize option. I'm not sure if you can remove options in major versions, or if they should be deprecated instead.

> The consumer creates a default thread pool of 10. You can configure the size but the pool is fixed.
> Wonder if we should use a bounded pool so we can have min-max so it can grow depending on demand. That is a bit hard to do as the thread pools in jdk isn't so good at this. 
> The spring-jms has a fair bit of logic to do this scaling up/down.
