Well it’s not like that. We don’t just purge. There are business rules which will decide the records to be purged or archived and then purged, so cannot rely on TTL.

It's an antibiotic pattern. What I would do would be to rely on TTL for removal of data and use the TWCS compaction strategy to handle removal and you just focus on insertion.

Is it better to Purge a large volume of data at regular intervals (like run A&P jobs once in 3 months ) or purge smaller amounts more frequently (run the job weekly??) Some estimates on the number of deletes performed would be…upto 80-90K rows purged in 3 months vs 10K deletes every week ??
