SORT_RO key [BY pattern] [LIMIT offset count] [GET pattern [GET pattern ...]] [ASC|DESC] [ALPHA]

Read-only variant of the SORT command. It is exactly like the original SORT but refuses the STORE option and can safely be used in read-only replicas.

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).

The SORT_RO variant was introduced in order to allow SORT behavior in read-only replicas without breaking compatibility on command flags.

See original SORT for more details.
