node db wat

mongo-like interface to rethinkdb

goals

• small efficient codebase
• high throughput atomic writes to disc/network (only write new data to disc)
• no write corruption on master data even during unexpected errors/faults.
• optional automatic passthrough to replicate or loadbalance

many many things.

usage:

// LOAD/CREATE DATABASE(S)
var nodedbwat = require("nodedbwat");
var db = nodedbwat.connect("", ["mydb", "anotherdb"]);

// SUBSCRIBE TO DB INSERT EVENTS FOR A REALTIME FEED
db.mydb.on("insert", function (entry) {
    
    // LOGS OUT EVENT
    console.log("insert event:");
    console.log(entry);
    
    // SAVE TO SSD
    db.mydb.save(); 

    // FIND DATA
    db.mydb.find({ car: "BAKKIE" }, function (err, results) {
        console.log(results);
    });
