A small embedded key value store for learning purpose

PocketDB

A simple embedded key value database. Currently only support put and get methods. This is definitely not production ready.

Put

Putting the data will store them in the JSON format to the provided location.

let mut db = open("mydb").unwrap();

db.put(b"Hello".to_vec(), b"World".to_vec());
db.put(b"Name".to_vec(), b"Aziz".to_vec());
db.put(b"Age".to_vec(), b"25".to_vec());

Get

Continuing on the put example, if you have already data present you can use the get method to get the value in the KeyVal struct.

let mut db = open("mydb").unwrap();

let kv = db.get(b"Hello".to_vec()).unwrap();
String::from_utf8(kv.val) // World

I don't support deleting the keys as of yet. I need to research how other databases do that. The objective here is to create a learning material which can teach others how to create a key value database with almost production grade.

A database is the heart of the software. Understanding them will make you a better use of them. Most of the projects uses a SQL powered relational database. But the relational databases under the hood uses a key value store to store their mission critical data.
