This ethos of this project is to:
- Create a fully functional ZeroMQ bridge which introduces minimal latency and maximum throughput when compared with a native ZeroMQ implementation.
- Create a bridge which is fully conformant with the latest OpenMAMA acceptance and unit tests.
- Give anything which would be useful for 'any old middleware bridge' back to the OpenMAMA core project.
NB: This project is MIT Licensed and in no way affiliated with nor supported by the OpenMAMA project or SR Labs - if you find any issues, please report to this project via github.
The current version of the bridge actually has comprehensive middleware bridge functionality. It has:
- Support for any serializable / deserializable MAMA Message payload bridge
- Reasonably good performance (more details to be confirmed...)
- Request / Reply Functionality
- Basic Publish / Subscribe
- Market Data Publish / Subscribe
- ZeroMQ TCP transport compatibility
In layman's terms, this means that it is fully compatible with:
- mamapublisherc / mamasubscriberc
- mamapublisherc / mamainboxc
- capturereplayc / mamalistenc
Which is pretty much all of the MAMA functionality that most people care about.
NB: This is very much in development and I will always be developing on the latest version of Fedora. If I have broken an OS that you use, please let me know.
- RHEL / CentOS 5
- RHEL / CentOS 6
- Windows 7+
The bridge depends on:
- MAMA / OpenMAMA
- Libevent
- Libuuid (Linux only)
- Scons
Until dynamic bridge loading is supported, you will also need to build against
my github fork of OpenMAMA (https://github.com/fquinner/OpenMAMA) on the
feature-omzmq branch which contains the middleware name and enum as well as
a couple of submitted-but-not-merged-yet openmama patches to allow the qpid
proton payload to work with other middlewares.
I will add the enum upstream at some point in the future too, but I plan on
using this bridge to help test the dynamic loading, so I'll not add the enum
to OpenMAMA master until that is ready.
If you have all the prerequisites, the build process should be pretty straightforward:
scons --with-mamasource=PATH --with-mamainstall=PATH
After building, you will have a libmamazmqimpl.so library created. Add the
directory containing this library to your LD_LIBRARY_PATH and run your
applications with -m zmq to use the bridge. Example mama.properties
transport configuration parameters are included in the code in the config
folder.
