Azouk Libraries

Azouk libraries contain:

Multiplexer
distributed Logging component

Multiplexer

Multiplexer is short for Azouk Enterprise Message Bus. It consists of

server that acts as a service broker,
client library,
abstract classes for writing Multiplexer-based backends and services

and provides fast, robust, fault-tolerant, asynchronous communication in distributed environment.

Both client library and backend classes are available in

C++
Python
Java (for Java client & server contact the project owners - they're ready but not yet released)

The communication format leverages Google Protocol Buffers. For gluing C++ and Python it uses Boost.Python. Asynchronous communication is handled with Asio.

Azouk Logging

Logging library is a rich-format logging based on Google Protocol Buffers. It consists of

client library that formats and renders log entries on both stderr and binary logging stream suitable for machine parsing;

fast
no overhead when log is not written
for both

C++
Python

log streamer that packs log entries from binary logging stream and sends them using Multiplexer
log collector that holds the log entries in memory and allows to search them.

C++ logging API leverages Boost.Preprocessor meta programming library. For gluing C++ and Python it uses Boost.Python.

Altough it's designed for general purpose, it serves well, and so we use it, to monitor and log events in a django-powered app.

Authors

Multiplexer and Azouk Logging were end-to-end designed and implemented by Piotr Findeisen as a part of his work for Azouk. Krzysztof Kulewski participated in the architecture overview.

Java client, Java server were designed and implemented ground up by Kasia Findeisen and Piotr Findeisen. Pure-Python client (a work in progress) is modelled after Java version and developed by Piotr Findeisen.
