#async_query_executorObject

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.

Use :ruby if you want to have different database adapters for, e.g., your development and test environments.
