Hi,

We are doing POC on Cassandra for o= ur business needs. We also need some kind of notification when a column/att= ribute is modified (insert/update/delete) of a table.

They are production rea= dy in the sens that they are fully functional. But using them require a *de= ep* knowledge of Cassandra Internal Write path and is dangerous because the= write path is critical.

Alternatively if you need a not= ification system of new mutation, there is a CDC feature, available since 3= .9 only (maybe not production ready yet)
