New sample project showing how to manage Universal Messaging DataGroups
A new Apama sample project shows how Apama can
Publish to Universal Messaging (UM) DataGroups
Dynamically manage the membership of UM DataGroups as clients, known as DataStreams, connect and disconnect to the UM server.
UM DataGroups use a publish/subscribe messaging technology, which has a lightweight grouping structure that allows a remote process to manage the data received by each client.
Note:
UM DataGroups use a completely different mechanism than the one used by JMS topics or UM channels, which can be accessed through Apama's correlator-integrated messaging for JMS or through UM native integration.
The new sample has two parts:
A suggested EPL event API to expose the DataGroup publisher and manager functionality. It is implemented using a correlator plug-in that is written in Java. Complete source code is provided.
A sample application that shows simple and advanced ways to use this API for publishing and/or managing DataGroups. This demonstrates the powerful combination of the Apama platform and the UM DataGroups feature.

Universal Messaging documentation.
