The LWES Light Weight Event System is a framework for allowing the exchange of information from many machines to many machines in a controlled, platform neutral, language neutral way. The exchange of information is done in a connectless fashion using multicast or unicast UDP, and using self describing data so that any platform or language can translate it to it's local dialect.
This leads to a system with the following features
- Fire and Forget messaging
- Decoupling of senders (emitters) from receivers (listeners, journallers)
- Centerless, no single point of failure
- Support for many to many communication where nodes can enter and leave the system at any time.
- Computer language and hardware platform independent
The system consists of two major components
- Emitter - a source of events, this is usually a server or process which wants to announce something
- Listener - a sink of events which deserializes and processes events on the fly as they are received.
There is also a custom listener which defers deserialization until some point in the future, and simply captures and writes the events to a log. This is in the lwes-journaller package, and is called a journaller.
This library is the C implementation of the LWES. There are also wrappers for various scripting languages, and a pure java implementation packaged separately. All are wire format compatible.
