[Discuss] Python cartridge agent for Stratos
Hi Devs,
We have discussed about the importance of a light weight cartridge agent in
several mail threads since existing agent had been written in Java and
running a Java runtime inside a cartridge instance is a performance
overhead as well as a costly operation. Here I would like to initiate that
(writing a Python based cartridge agent) with the requirements which mainly
required for it.
First of all we have to implement Python clients for the communication
mechanisms used in agent. Cartridge agent mainly use two communicate
mechanisms,
1. Communicate with Complex Event Processor using thrift
2. Communicate with Message Broker using AMQP
To full fill the requirement #1, we have to write a python thrift client
and I'm currently working on it.
Highly appreciate your thoughts on this.
Thanks,

Great stuff!! Very neat code Dinesh! :-)
May be you could add some notes to the README file about the Thrift Python
packages that the client is referring, how they are maintained.
