Redis 2.8 (standard architecture) and Redis 4.0、5.0/6.2 (standard and cluster architectures) support the append, bitcount, bitop, bitpos, decr, decrby, get, getbit, getrange, getset, incr, incrby, incrbyfloat, mget, mset, msetnx, psetex, setex, set, setbit, setnx, setrange, strlen, and bitfield commands. Redis 4.0 and 5.0 don’t support the getdel and getex commands, and Redis 6.2 supports the getex command.
Redis 2.8 standard architecture doesn’t support the bitfield, bitfield_ro, and stralgo commands.
In a cluster architecture, cross-slot access is applicable to the mget and mset commands other than the bitop and msetnx commands.
As new command for Redis 6.2, the bitfield_ro command is supported for both architectures, but the stralgo command is only supported for the standard architecture.
In the following table, ✓ indicates "supported", x indicates "unsupported", and - indicates that cross-slot access is not applicable to the command:
