I haven't tried CDC either.
Read about it at an abstract level.
Suggested it as an option for exploration.
We too use trigger on production to indicate which primary key has been
acted(update/insert/delete) upon.

Using CDC is going to be... difficult. First off (to my knowledge) all you
get is a CommitLogReader. If you take a look at the Mutation class
(everything is serialized and deserialized there), there's no user
reference. You only get a keyspace, key, and a PartitionUpdate, which
don't include any
Hi Siddharth Verma,
We explored this option, it seems it outputs the change only to a log file
and we cannot get notified to a listener class. Could you please provide us
what kind of information is pushed in the commit log and when we should
read commitlog. Do we need to instantiate CommitLogRead
Hi, I've got a strange behaviour when adding a new DC to my Cassandra
cluster.
Cassandra version is 2.1.8.
The topology is a 3 DC cluster (let's call it A, B, C) and I have 3 users
(1 superuser, 2 non-superuser)
I'm adding a new DC (let's call it D) with 1 node, so I started it with
auto_bootstr
Hi Jon,

Hi Sathish,
You could look into, Change Data Capture (CDC) (

cqlsh uses the Python driver, I don't see how there would be any way to
differentiate where the request came from unless you stuck an extra field
in the table that you always write when you're not in cqlsh, or you
modified cqlsh to include that field whenever it did an insert.

Hi,
We are planning to use ITrigger to notify changes, when we execute scripts
or run commands in cqlsh prompt. If the operation is performed through our
application CRUD API, we are planning to handle notification in our CRUD
API itself, however if user performs some operation(like write operatio
Hi guys,
we are making a simple tool which allows us to transform table
