| # MDEV-22232: CTAS execution crashes during replay.
 | |
| #
 | |
| # There were multiple problems and two failing scenarios with empty result set
 | |
| # and with non-empty result set:
 | |
| # - CTAS didn't add shared keys for selected tables
 | |
| # - Security context wasn't set on the replayer thread
 | |
| # - CTAS was retried after failure - now retry disabled
