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 primary 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.
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).
