A minimal Redis clone written in Go — supports a subset of the Redis protocol (RESP).

• RESP protocol parsing
• Basic commands:
• PING – Ping the server and will reply with PONG
• SET key value – Store a value by key
• GET key – Retrieve a value by key
• DEL key – Delete a key
• EXPIRE - Set timeout on a key
• TTL - Return remaining time to live of a key that has a timeout.
• KEYS - Return all keys matching pattern
• HSET key field value – Set hash field
• HGET key field – Get hash field
• HDEL key field – Delete specified field from the hash
• HGETALL key field – Delete specified field from the hash
• expiration cleanup
• disk storage for persistent across restart

127.0.0.1:6379> SET foo bar
OK

127.0.0.1:6379> GET foo
"bar"

127.0.0.1:6379> DEL foo
(integer) 1

(nil)

• written in pure Go
• parses raw Resp manually
• handle each connection with go routines
• uses map[string]string internally for storage
• Uses min heap data structure to hold data with timeout
