Hi Gayan, What are the concerns/blockers for using Apache Qpid Proton-C library [1] with Python binding?
As I understood, this is cross-platform compatible (Linux/Windows) and you do not need Java. However, there is a pure Java implementation but we can use C/Python binding. We will have to investigate this further though. Have we made an analysis of using STOMP vs AMQP as the communication protocol with MB for cartridge agent? We might have to consider this because with the upcoming Docker support there can be about 1000+ instances communicating with the MB.
