memdb

a minimalistic key/value store implemented in Go.

NOTE: I wrote this project for learning purposes. It may not be completely thought out and error free. Use at Your Own Risk.

---

inspired by redis, this project provides a key/value data store intended to hold a small amount of data within memory.
!!! No intended to be used for large data storage !!!

How it works

A tcp server listening and accepting connection on port 8000 per default. The client can send a variety of command that follows this pattern

  COMMAND KEY VALUE TTL VALUE

Available commands:

• SET key value [TTL value]\n
• GET key\n
• REMOVE key\n
• INC key value\n
• DEC key value\n
• NEGATE key\n
• LAPPEND key value\n
• LREMOVE key value\n

Responses follow this pattern:

Type Length\r\n
value

Response types are special characters identifiers:
+ string
: integer
# boolean
* list
- error

value can be a string, integer, boolean or a list

examples:

SET command

SET key value
Ok

GET command

GET example
+5
value

SET command for list type

SET example [2,3,4,[test,5,7]]
Ok

GET command for list type

*16
[2,3,4,[test,5,7]]

Install

go install github.com/Wa4h1h/memdb/cmd/keydb@latest
