General purpose Python framework for writing highly scalable applications

Project Description

General purpose Python framework for writing highly scalable applications.

About

A typical application consists of several modules. Each module has its own process, stores a pidfile in ‘tmp/pids’, and has a logfile in ‘logs’.

A RPC protocol is implemented on top of zeromq in order to allow for inter-module communication. Modules have an auto-adjustable number of workers in order to cope with a high number of requests. These rpc requests will block until that module becomes available. Read more about zeromq at http://zguide.zeromq.org/

Each module consists of several gevent greenlets. A basic module will already contain a few greenlets that handle incoming rpc requests. You can spawn additional greenlets for your own needs. Read more about gevent at http://www.gevent.org/

Tasks

You can manage and debug your modules using built-in tasks. Type ‘cake’ at a bash prompt when inside your project to see available tasks and what they do. You can also define your own taks.

Commands

To create a new project:

$ pyscale new <name>

To generate a new module:

$ pyscale generate <name>

To start, stop, debug, view logs and more check out available cake tasks:

$ cake
$ cake start
$ cake stop
$ cake status
$ cake log
$ cake console

Usage

To execute an rpc request on another module:

self.sock('modname').method(*args, **kwargs)

You can also use properties, and chain requests:

self.sock('modname').prop.method()

You can also issue requests on all available modules:

self.multisock('*').method()

To spawn another greenlet in a module either use the ‘job’ decorator or:

self.jobs.spawn(func)

To debug your application use logs and the console.
