Query Store Bug

Brent Ozar reports on a bug in Query Store in Standard and Express editions:

If you’re using SQL Server 2016’s awesome new feature, Query Store, there’s a new bug with automatic cleanup. Books Online explains:

Automatic data cleanup fails on editions other than Enterprise and Developer. Consequently, space used by the Query Store will grow over time until configured limit is reached, if data is not purged manually. If not mitigated, this issue will also fill up disk space allocated for the error logs, as every attempt to execute cleanup will produce a dump file.

Here’s hoping that bug gets fixed quickly.
