Hi All,
Making "transaction" like is my actual preoccupation of the moment.
My (simplified) need is :
- update data in column family #1
- insert data in column family #2
My need is to see these operations in a single "transaction" because the
data is tightly coupled.
I use zookeeper/cage to ma
A write for a single row is atomic, including writing to multiple CF's in with
the same row key. http://wiki.apache.org/cassandra/FAQ#batch_mutate_atomic
They are not isolated though, reads may see the write partially applied.
Have a look at the data modelling slides here

Hi Aaron,
Thank's for your answer.
In my case, insertions on my multiple CF's are not on the same key.
I've ever read the presentation you advise to me and i think that write
transaction log in a special CF is the track i will follow to try to solve
my problem.
Cheers,
