> We observed a significant resource usage when using many ES controller
> service instances. After investigation, it appears that the ES client relies
> on a RestClient where the Apache Http Async Client starts by default one
> dispatcher thread, and a number of worker threads used by the connection
> manager, as many as the number of locally detected processors (depending on
> what Runtime.getRuntime().availableProcessors() returns).
> I think it'd be worth adding this in the documentation and the proper
> annotation where relevant.
