# 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
