#About

ueberDB is a abstraction layer for databases. It turns every database into a simple key value store, at the moment we only support mysql and sqlite. ueberDB uses a smart cache and buffer algorithm to make databases faster. Reads are cached and writes are done in a bulk. The bulk writing reduces the overhead of a database transaction.

#Install

`npm install ueberDB`

#Example


var ueberDB = require("ueberDB");


//mysql

var db = new ueberDB.database("mysql", {"user":"root", host: "localhost", "password":"", database: "store"});

//sqlite in-memory

//var db = new ueberDB.database("sqlite");

//sqlite in file

//var db = new ueberDB.database("sqlite", {filename:"var/sqlite3.db"});

//sqlite in file with a write interval of a half second

//var db = new ueberDB.database("sqlite", {filename:"var/sqlite3.db"}, {writeInterval: 500});

//initialize the database

db.init(function (err)

{

  if(err) 

  {

    console.error(err);

    process.exit(1);

  }

  //set a object as a value

  //can be done without a callback, cause the value is immediately in the buffer

  db.set("valueA", {a:1,b:2});

  

  //get the object

  db.get("valueA", function(err, value){

    console.log(value);

    

    db.close(function(){

      process.exit(0);

    });

  });

});



#How to add support for another database

Look at sqlite_db.js and mysql_db.js, your module have to provide the same functions. Call it DATABASENAME_db.js and reimplement the functions for your database. If you think it works, test it with `node benchmark.js DATABASENAME`. Benchmark.js is benchmark and test at the same time. It tries to set 100000 values. You can pipe stderr to a file and will create a csv with benchmark results.
