Renato Javier Marroquín Mogrovejo commented on GORA-214:
--------------------------------------------------------
Hi Roland,
Just a few questions and quick comments about your patch man.
1. Do you know if there is any advantage or drawback from using the methods for
defining column names as strings vs ByteBuffers?
2. When should the executeMutator method be called? at flush time? (I guess we
should as well right?) or will we also expose some part of the api for letting
the users handle this?
I haven't downloaded it yet, but I will do it tonight and give a closer look at
it ;)
Thanks again for this.

> Cassandra & Hector offer a lot of possibilities to batch mutations together.
> This means Hector will not send data out to Cassandra until it receives the
> command to do so [execute()].
> Really useful is this feature if you have to addOrUpdate two or more columns
> for one key (in one cf), it will then limit load on Cassandra, too.
> A small prove of concept patch against 0.2 is attached.
