Performs arbitrary read-only bitfield integer operations on strings.
BITFIELD_RO key [GET encoding offset [GET 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 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.
BITFIELD_RO hello GET i8 16Array reply: each entry being the corresponding result of the sub-command given at the same position.
O(1) for each subcommand specified
