A Key/Value Store written in PHP

SlowDB

, _(*1)

When you don't want Redis, Memcached, or any other Key/Value store., _(*2)

SlowDB is the Key/Value store written purely in PHP that'd you be upset to find your co-worker running in production., _(*3)

Features:

• Multiple named Collections
• In-memory indexes
• Safe persistence to disk

SlowDB allows for storing Key/Value pairs in multiple collections. Indexes are built/rebuilt on startup to map Keys to file locations on disk. This allows performant binary searches across database files and writing directly to disk for safe, consistent writes., _(*4)

Installation

Clone the repository locally and run composer install:, _(*5)

$> git clone https://github.com/kmfk/slowdb
$> cd slowdb/
$> php composer.phar install

Usage

Technically, SlowDB can be instantiated as a service in your application., _(*6)

However, when SlowDB is used as a service, the Database needs to be instantiated and the indexes built on every request. On small datasets, this should be negligible - while large datasets, this can add unwanted latency to requests., _(*7)

The best way to use SlowDB is by using the included socket server (built on ReactPHP) and the driver., _(*8)

While only single threaded, this will keep the database indexes in memory and provide better performance., _(*9)

$> ./slowdb &

Basic Example

Once the server is running, you can use it like this:, _(*10)

    <?php

    require 'vendor/autoload.php';

    use SlowDB\Driver;

    $driver = new Driver('localhost', 1337);

    $driver->test->set('abc', ['foo' => 'bar']);

    $value = $driver->test->get('abc');

    print_r($value);
