> [HIVE-4617|https://issues.apache.org/jira/browse/HIVE-4617] provides support
> for async execution in HS2. The async (background) thread pool currently
> creates N threads (server config), which are alive all the time. If all the
> threads in the pool are busy, a new request is added to a blocking queue.
> However, we can improve the strategy by not having all the async (background)
> threads alive when there are no corresponding requests. The async threads
> should die after a certain timeout if there are no new requests to handle.
