    #async_query_executor   (rw)
  



  

    

Sets the async_query_executor for an application. By default the thread pool executor set to nil which will not run queries in the background. Applications must configure a thread pool executor to use this feature. Options are:



* nil - Does not initialize a thread pool executor. Any async calls will be
run in the foreground.
* :global_thread_pool - Initializes a single Concurrent::ThreadPoolExecutor
that uses the async_query_concurrency for the max_threads value.
* :multi_thread_pool - Initializes a Concurrent::ThreadPoolExecutor for each
database connection. The initializer values are defined in the configuration hash.
