sort_ro.3valkey - Man Page

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 Valkey command table. For this reason read-only replicas in a Valkey Cluster will redirect it to the master instance even if the connection is in read-only mode (see the READONLY command of Valkey 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.

valkey-protocol(7) Array reply: a list of sorted elements.

O(N+M*log(M)) where N is the number of elements in the list or set to sort, and M the number of returned elements. When the elements are not sorted, complexity is O(N).
