@Async groups [SPR-9318]

[spring-projects-issues]

Bozhidar Bozhanov opened SPR-9318 and commented

Currently all @Async methods are executed using the same thread pool. But often you need different groups of related async operations and you don't want them to share the same pool. For example, a scheduled job may want to asynchronously invoke a method multiple times, but if it uses @Async it will consume all the threads that are supposed to be used by other processes.

That's why I suggest to add an async group. @Async(group="main"), @Async(group="calculations"), etc. Each of them will have a separate pool.

<task:executor id="mainExecutor" pool-size="100" group="main" />
<task:executor id="calcExecutor" pool-size="20" group="calculations" />
<task:annotation-driven executors="mainExecutor,calcExecutor" /> (or a nested <list>)

Hi Bozhidar, #11513 should take care of your use case here. If not, please comment there and explain. Thanks!
