bitfield_ro.3valkey - Man Page

Performs arbitrary read-only bitfield integer operations on strings.

Synopsis

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

Description

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 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).

See original BITFIELD for more details.
