Listen for Changes In Cassandra Datastore?

Question

I wonder if it is possible to add a listener to Cassandra getting the table and the primary key for changed entries? It would be great to have such a mechanism.

CDC

"In databases, change data capture (CDC) is a set of software design patterns used to determine (and track) the data that has changed so that action can be taken using the changed data. Also, Change data capture (CDC) is an approach to data integration that is based on the identification, capture and delivery of the changes made to enterprise data sources." -Wikipedia

As Cassandra is increasingly being used as the Source of Record (SoR) for mission critical data in large enterprises, it is increasingly being called upon to act as the central hub of traffic and data flow to other systems. In order to try to address the general need, we, propose implementing a simple data logging mechanism to enable per-table CDC patterns.
