Insight in AsyncOperationBase needed?

If you're asyncoperationbase has grown beyond 1.000.000 records, then you most likely want to clean this up for performance reasons.

You can just jump to the Microsoft KB article and run some scripts to clean this up, but you might also want to do some more research upfront to avoid getting into this situation again. Our friends at PowerObjects have written a nice article about this. Another approach would be to run the script below. This shows the most common events (more than 10.000 entries) that are stored in the table. The last column indicates if these records will be removed using the Microsoft KB article.

If you want to filter events based on the amount of occurrences, then you can simply change the threshold.


declare @threshold as int

set @threshold = 10000

DATEPART(MONTH,CreatedOn) AS [Month],
