NEW QUESTION # 229
You have an Azure SQL database.
You discover that the plan cache is full of compiled plans that were used only once.
You run the select * from sys.database_scoped_configurations Transact-SQL command and receive the results shown in the following table.
You need relieve the memory pressure.
What should you configure?
Answer: B
Explanation:
OPTIMIZE_FOR_AD_HOC_WORKLOADS = { ON | OFF }
Enables or disables a compiled plan stub to be stored in cache when a batch is compiled for the first time. The default is OFF. Once the database scoped configuration OPTIMIZE_FOR_AD_HOC_WORKLOADS is enabled for a database, a compiled plan stub will be stored in cache when a batch is compiled for the first time.
Plan stubs have a smaller memory footprint compared to the size of the full compiled plan.
