Build Your Own Database

A simple key value store I built as a learning-project. Not intended for production, use a proper database for that ;).

Installation

With go installed, compile the code:

go build

Usage

REPL

The REPL is started by starting the program without any other CLI commands:

./byod

Store Data

Inside the REPL type PUT followed by a key and a value:

PUT hello world

the database will respond with a success or error message.

Retrieve data

In the REPL type GET followed by a key:

GET hello

the database will respond with a success message containing the most recent value stored for that key. In case of error an error message will be printed.

CLI

Store Data

./byod put [key] [value]

Retrieve Data

./byod get [key]

Configuration

Configuration is stored in a .env file. See .env.sample for config option names and example values.

TODOS

  • Proper console / REPL using a readline library
  • CLI interface
  • ACIDity
  • Indexing
  • Transactions
  • HTTP interface
  • Dockerization
  • Distributed cluster mode

… and much, much more.
