This project now has complete MAMA middleware bridge functionality. It passes all of the OpenMAMA middleware unit tests and provides:
- 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
- ZeroMQ PGM (multicast) transport compatibility
- ZeroMQ IPC (named pipes) transport compatibility
You can expect the pub / sub / request / reply example apps to work great out of the box:
- mamapublisherc / mamasubscriberc
- mamapublisherc / mamainboxc
- capturereplayc / mamalistenc
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+
- Windows 7+
The bridge depends on:
- MAMA / OpenMAMA
- Libevent
- Libuuid (Linux only)
- Scons
As of the 2.4.0 release of OpenMAMA, there is no longer a requirement to build this library off my own special fork of OpenMAMA. Instead thanks to dynamic bridge loading support, you can now build this off the master branch of OpenMAMA. I may also make binary releases available soon.
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.
If you want to use the omnm payload (less functionality but faster than qpid), you can have a look at the omnm github page to find out how.
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.
