- Available since
- 6.0.0
- Time complexity
- O(1) for each subcommand specified
- ACL categories
- @read, @bitmap, @fast
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 Redict command table.
For this reason read-only replicas in a Redict Cluster will redirect it to the master instance even if the connection is in read-only mode (see the READONLY
command of Redict Cluster).
Since Redict 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.
