BITFIELD_RO key GET encoding offset [ encoding offset ...]

Read-only variant of the BITFIELD command. It is like the original BITFIELD but only accepts GET subcommand and can safely be used in read-only replicas.

Since the original BITFIELD has SET and INCRBY options 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).

Since Redis 6.2, the BITFIELD_RO variant was introduced in order to allow BITFIELD behavior in read-only replicas without breaking compatibility on command flags.

See original BITFIELD for more details.

Examples

BITFIELD_RO hello GET i8 16

Return

Array reply: An array with each entry being the corresponding result of the subcommand given at the same position.
