Mesos RxJava

Mesos RxJava is a library that provides a Reactive Client (via RxJava) atop Apache Mesos' new HTTP APIs.

Background

Apache Mesos is a Cluster Resource manager providing access to cluster resources such as CPU, RAM, Disk and Ports. In order to leverage these computing resources a program called a framework is created and registers with Mesos. Once registered a framework can launch tasks using the resources offered by Mesos.

In an effort to allow Mesos to be more accessible to more languages, HTTP APIs are being developed to allow polyglot access to authoring frameworks. Prior to the HTTP APIs, libmesos (C++ library) had to be used.

Project Goal

This project's primary goal is to provide a Java client for interacting with these new HTTP APIs. Mesos' HTTP APIs are modeled as an event stream; as such a scheduler can be modeled as an rx.Observable<Event>. Once created, the scheduler is able to use the powerful stream manipulation functions provided by RxJava to react to events.
