We've had Dynamics 365 now for a little over 3 years. I've had systems jobs that cleanup AsyncOperationBase for awhile, now there's 666K records in there, which isn't bad but it's taking up over 17GB in storage.
From what I've read online it's because of the [data] property on the table. Is there any issue with running a SSIS Kingswaysoft job to clear out that data field to free up space? Nobody looks at those system jobs in production, I am the only one when I try to track down flow errors and it's not very often.
Anything existing can be cleaned out for now, as far as what's remaining and that field property.
