You have an Azure SQL database named sqldb1.

You need to minimize the possibility of Query Store transitioning to a read-only state.

What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: B

The Max Size (MB) limit isn't strictly enforced. Storage size is checked only when Query Store writes data to

disk. This interval is set by the Data Flush Interval (Minutes) option. If Query Store has breached the maximum

size limit between storage size checks, it transitions to read-only mode.

Incorrect Answers:

C: Statistics Collection Interval: Defines the level of granularity for the collected runtime statistic, expressed in

minutes. The default is 60 minutes. Consider using a lower value if you require finer granularity or less time to

detect and mitigate issues. Keep in mind that the value directly affects the size of Query Store data.

I remember something about the Data Flush Interval affecting how often data is written to the Query Store, but I'm not sure if halving it is the right move.
