What maps to what: migrate from Memcached to KiviDB

What maps to what. Migrate to KiviDB: Move from Redis, Valkey, ElastiCache, Redis Cloud, Aiven, Aerospike, Hazelcast and more: getting the data out, loading i

Memcached	KiviDB	Notes
Text, binary or meta protocol	RESP2, RESP3	Change the client library. Any Redis client works.
`get`	`GET`
`get k1 k2 ...` (multi-get)	`MGET k1 k2 ...`	`MGET` returns a value or nil for every key, in order.
`set k v` with exptime	`SET k v EX <seconds>`
exptime over 30 days (a Unix time)	`SET k v EXAT <unix-time>`	See Expiry below.
`add`	`SET k v NX`	Only if the key does not exist.
`replace`	`SET k v XX`	Only if the key exists.
`append`	`APPEND`
`prepend`	No single command	Read and write back in a `WATCH`/`MULTI`, or keep a list and `LPUSH`.
`incr` / `decr`	`INCRBY` / `DECRBY`	See Counters below.
`touch`	`EXPIRE`
`gat` (get and touch)	`GETEX k EX <seconds>`
`gets` + `cas`	`WATCH` / `MULTI` / `EXEC`, or `SET ... IFEQ`	See Compare-and-set below.
`delete`	`DEL`
`flush_all`	`FLUSHDB` / `FLUSHALL`
Client flags (32-bit per item)	No equivalent	See Client flags.
`stats`	`INFO`
Slab allocator, LRU per slab class	One memory limit (`maxmemory`) and an eviction policy
Client-side consistent hashing over many servers	One server, or a cluster	See More than one server.
No persistence	Snapshots and an append-only file	Optional.
Strings only	Strings, hashes, lists, sets, sorted sets, streams, JSON, search, vectors	You can stop serializing whole objects into one string later; you don't have to.
SASL (binary protocol), or `-Y` auth file (text protocol, experimental)	`AUTH` with a password, or ACL users
TLS (when built with it)	The `tls` and `full` builds; always available on KiviDB Cloud
