- ACL categories:
Since the original
SORT has a
STORE option it is technically flagged as a writing command in the Redis command table. For this reason read-only replicas in a Redis Cluster will redirect it to the master instance even if the connection is in read-only mode (see the
READONLY command of Redis Cluster).
SORT_RO variant was introduced in order to allow
SORT behavior in read-only replicas without breaking compatibility on command flags.
