Redis Protocol (RESP)

Talon's Redis-compatible interface for KV operations using any Redis client.

Overview

Talon implements the Redis RESP protocol, allowing any Redis client library to connect and perform KV operations.

Connection

redis-cli -p 6380

Supported Commands

SET key value [EX seconds]
GET key
DEL key [key ...]
MSET key1 value1 key2 value2
MGET key1 key2
SETNX key value
GETSET key value
APPEND key value
STRLEN key
GETRANGE key start end
SETRANGE key offset value
INCR key
INCRBY key increment
DECR key
DECRBY key decrement
INCRBYFLOAT key increment

Key Operations

EXISTS key
EXPIRE key seconds

RENAME key newkey
TYPE key
RANDOMKEY
KEYS pattern

Example

$ redis-cli -p 6380
127.0.0.1:6380> SET user:1 '{"name":"Alice","age":30}'
OK
127.0.0.1:6380> GET user:1
"{\"name\":\"Alice\",\"age\":30}"
127.0.0.1:6380> EXPIRE user:1 3600
(integer) 1
127.0.0.1:6380> TTL user:1
(integer) 3599
127.0.0.1:6380> INCR counter
(integer) 1
127.0.0.1:6380> KEYS user:*
1) "user:1"

Limitations

• Only KV operations are supported via Redis protocol
• No Redis data structures (List, Set, Hash, Sorted Set)
• For full engine access, use the HTTP API or embedded Rust API
