SQL Query Store qds_async_queue
Please note that the official documentation is the official source of information.
I took a brief look and this shouldn't be taken as an extreme look from every possible angle.


The wait type is benign as it's a permanent task that which is persisting QDS data in the background. The wait shows up and is incurred while the instance is up and running, it will have more incurred wait if there are items to persist and lower if there are less items to persist.

So, overall, unless there are other issues going on, this wait type can be ignored.
