- Usage:
-
SORT_RO key [ BY by-pattern ] [ LIMIT offset count ] [ GET get-pattern ] [ [ GET get-pattern ] ... ] [ asc | desc ] [ sorting ]
- Complexity:
- 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).
- Since:
- 7.0.0
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.
Examples
SORT_RO mylist BY weight_*->fieldname GET object_*->fieldname
