Tuning for Refresh
Scenario
When a refresh operation is running, system performance is affected and user queries get rejected. You want to reduce the memory usage of the refresh job.
Solution
Set the MEMORYSIZE parameter of the refresh pool to a fixed value. The Resource Manager then tunes the refresh query to only use this amount of memory.
Tip: Remember to reset the refresh pool MEMORYSIZE back to 0% after the refresh operation completes so memory can be used for other operations.
