Welcome to QWAZR

QWAZR is a set of microservices dedicated to scalable, failover, distributed projects.

By building QWAZR, our goal is to provide an easy and efficient way to build scalable applications that require both distributed processes and fail-over abilities.

What do you get (production ready) ?

This project is a work in progress. The current version of QWAZR (1.0.1) comes with the following services:

Webapps : A model-view-controller application server,
Scheduler: A multi-master scheduler,
Scripts: A distributed JAVA/Javascript job service,
Library : A set of connectors and tools to link your application to the outside world (Cassandra, MongoDB, MySQL, HDFS, LDAP, FTP, etc.) and data management (language tools, markdown to HTML converter, Freemarker, XML parser and writer, etc.).
Crawlers : A distributed (web) crawler,
Extractor : Text extraction from various kinds of binaries files,
Search: Full-text indexation and search based on Lucene,
Database: A NoSQL key/value database based on LevelDB.
Cluster : Manages the cluster's nodes.

Getting started

The Search microservice is currently available as a stand-alone Docker image.

Here is two examples of QWAZR applications which can be used as tutorials. By running one of this 5 minutes tutorials you will create a small web site, a REST/JSON API connected to a MongoDB database.

Our roadmap

Multi-master clustering

Deployed on several servers, the (multi) masters and the nodes work together, sharing the required information to provide a fault-tolerant distributed environment.

Full set of JSON API for each module

The server also provides a set of JSON REST web services that manages distributed jobs, web applications and data persistence.

Fast Javascript engine and automatic JAVA compilation

The Javascript and The JAVA source code can be updated without having to restart the server. The source code is automatically compiled without having to restart the application server.

A comprehensive documentation

The purpose of this Wiki.

Releasing the last modules:

Graph : A graph engine,
Store: A file management service with distribution and replication support,

Open Source & contributions

We believe that open source is a smart way to build amazing software. QWAZR is provided under the Apache 2.0 license.

There are many ways to contribute to the project:

The source code is here, you may fork, compile, develop and provide patches.
API Javadocs
We are currently writing the documentation in the source pages. You may suggest subjects, tutorials, etc.
