Is it possible to determine the keyspace and/or table in a digest mismatch log message?

I have many Digest mismatch messages in my debug.log and I know this typically happens during a Read repair process but the log message typically does not refer to a Keyspace nor a Table which has caused the Read repair to be initiated.

Sample:

DEBUG [ReadRepairStage:42] 2020-12-01 12:43:59,397 ReadCallback.java:244 - Digest mismatch:
org.apache.cassandra.service.DigestMismatchException: Mismatch for key DecoratedKey(5316686551650299872, 0000000670b33dd0) (6d6d385d0619780143abdd514670af43 vs 52e0d02214bde56a28d3729f9d6448b8)

Is it possible from the log message above to track the read repair back to a specific keyspace and/or tables?

Unfortunately, no. It isn't possible to deduce the inconsistent table from the digest mismatch message logged.

There isn't enough information in that debug message to extract that level of detail. Cheers!
