Query Store Storage Options

Erin Stellato looks at Query Store storage options, specifically MAX_STORAGE_SIZE:

Now, there are catalog views that allow you to view the Query Store data.  You can copy that data into another database using SELECT INTO, and then do comparisons, but wouldn’t it be nice to have some kind of export option?  There’s a Connect item for that:

Export Query Store tables separately from the database tables: https://connect.microsoft.com/SQLServer/feedback/details/2620017/export-query-store-tables-separately-from-the-database-tables

If you think this is something that would be useful for Query Store, please up vote it!  Again, Query Store is available in ALL editions of SQL Server 2016, this is definitely a feature you CAN use and will want to use!  This potential option won’t make it into RTM, but with the change in how SQL Server is releasing CUs, the more important the SQL Server team sees this option (as a result of votes), the faster it might make it in a release.

Query Store is one of the most exciting features for database administrators to hit in quite a while.  There will be some V1 pains, but this feature is well worth the upgrade to 2016.
