Detailed Description

This is the Cassandra Client which is used to create a connection to cassandra db.

All ZMF Events (only the pub/sub ones) will be stored in the database. We use the Apache Cassandra DB in latest version (2.1.x). To create a connection to cassandra db, you have to install the cassandra db driver on your system!
