Hi Nate,
Thank you.
I can give it a try.
Any examples you can point me to using QueryProcessor to read operations
from the CommitLogs?
Best regards,

QueryHandler (I called it QueryProcessor incorrectly in my initial
reply) is server side:

I must say that it is really encouraging to get your thoughts.
Thanks a ton Benjamin, Jacques-Henri, Jordan Nate and Chris.
I do not have access on the client side where the CQL is executed.
One of my requirements is that my app should not to affect the performance

There are different way of keeping your 2 database in sync. Unfortunatly,
they all have some trade offs (as always ;-))

Have you explored the QueryProcessor interface? That is a legitimate
extension point and may be a more suitable layer at which to
integrate.

There are different kinds of tombstones, a partition tombstone is held in
the MutableDeletionInfo of the PartitionUpdate that you can get from
deletionInfo() method which returns the private deletionInfo field from the
holder. There are also row and cell deletions so you have to handle each of

Hi Bejamin,
Nice to hear from you.
My goal is to reconstruct the CQL operation from the Mutation object.
So that I can trigger the same action on another NoSQL target like MongoDB.
Please let me know know if you have ideas?
Many thanks.

Hi Sanal,

INSERT or UPDATE operation?
I'm not sure it's possible to distinguish them - both of them just add data to
SSTable.
