BoJack

The unreliable key-value store

Status

Originally, from my article " Why you should build your own NoSQL Database ". BoJack is a bit mature now, yet missing several important features:

  • Cluster-friendliness
  • Security Layer (#34)
  • Unix Socket support (#48)

Feel free to share your thoughts and.

Installation

Requirements

  • The latest version of Crystal (0.24.x)
  • LLVM development files

Steps

git clone https://github.com/marceloboeira/bojack
cd bojack
make install

Showtime

bojack server
bojack client
$ bojack console
> set food :sushi:
:sushi:
> get food
:sushi:
> ping
pong

By default BoJack runs at 127.0.0.1:5000.

Usage

CLI

Currently the command-line interface supports two commands: server and console .

bojack <server/console> <flags>

Server

flag description --hostname Hostname the server will run 127.0.0.1 --port Port the server will run 5000 --log Path for a log file STDOUT --log-level Level of messages logged DEBUG = 0, INFO = 1 (default), WARN = 2, ERROR = 3, FATAL = 4

Console

flag description default --hostname Hostname this console will connect 127.0.0.1 --port Port this console will connect 5000
