"Write query aborted due to concurrent operation running on the table"

Not sure if anyone has seen this error before. It recently appeared on a high-write service that I have

Does your workload involve any ALTER or TRUNCATE table calls?

That error should only happen if there was some DDL going on concurrently (very rarely you may see that error).

No, there’s no ALTER or TRUNCATE happening. It’s a high rate of upsert statements.

What’s the best way to go about generating a cluster report?
