you want to use Cassandra vs a RDBMS if you
really want transactions.

Now I Understand, thank you.

Ok in this particular context it means no dependencies.
Thanks for your precision.
Kind regards,

No, it just means they don't have dependencies on each other. In this
case, it means
"orthogonal" means "90 degrees". Two lines are orthogonal if the
cross at 90 degrees.
Two ideas are orthogonal means that they are not compatible.
Transactions is orthogonal with Cassandra's design means that it will
require a lot of work and trade-off to implement transactions into
Cassandra.
Do you mean orthogonal like Commit and Rollback?? For example after we
perform Rollback, hence we cannot going back.

I do not understand what is the meaning of "needs to turn 90 degrees"??
Thank you.
On Sun,
"orthogonal" means "go to the opposite direction, but without going
back". Including "transaction" in Cassandra needs to turn 90 degrees
the design of Cassandra.
Kind regards,
Benoit.

Sorry, Would you want to tell me what is an orthogonal mean in this
context??
honestly I do not understand what is it.
Thank you.

You might also consider using a Software Transactional Memory[1] approach. I
haven't personally tried it, but there is a Scala/Java framework named Akka
that provides both STM features and Cassandra support. Should be worth a
look. Here's a nice write-up from someone who has already done some

No, as far as I know no one is working on transaction support in Cassandra.
Transactions are orthogonal to the design of Cassandra[1][2], although a
system could be designed incorporating Cassandra and other elements a la

Hi all,
I need transaction support on cassandra, so wondering is anybody work on it ?
