Nectar client - New Cassandra Client for .Net
I'm happy to announce Concord has decided to open source our port of Hector
to .Net.
The project is hosted on google code
https://code.google.com/p/nectar-client/
I'm still adding code documentation and wiki pages. It has been tested
against 1.1.x, 2.0.x
thanks
peter

I've studied DataStax .Net driver and it doesn't satisfy all of my needs. I
wish it met 50% of my needs, but it doesn't. In theory, Nectar could use
the DataStax .Net driver for native protocol, but I'd have to do a lot more
work to make it fit with Hector's API. Some use cases can stick with CQL
for 100%, but not the kinds of use cases I have.
The modeler we built for Cassandra takes advantage of types, generics, Solr
and tries to make it more friendly. We provide a JPA like interface for
running queries and behind the scene the framework executes the queries
against solr and cassandra. I know with DSE you can do a similar thing, but
the developer has to build multiple queries themselves and tell cassandra
to query solr. We take a model driven approach, so our schema modeler knows
how to take advantage of the framework to run queries with "like" clauses.
To the developer it's 1 query, not n queries.
hopefully DataStax will accept my talk for september and we can show the
stuff we built.

Peter,
There's very little reason today to write your own Cassandra driver for
.net, java, or python. Those firms that do are now starting to wrap those
drivers with any specific functionality they might require, like Netflix,
for example. Have you looked at DataStax's .NET driver?

thanks for the correction. Maybe it's just me, but I wish the
implementation were also in apache's repo. It's not a big thing, but having
multiple github forks to keep track of is a bit annoying. I'd rather spend
time coding instead of screwing with git on windows.

The native protocol specification has always been in the Apache Cassandra
repository. The implementations are not.

There's nothing preventing support for native protocol going forward. It
was easier to go with thrift and I happen to like thirft. Native protocol
is still relatively new, so I'm taking a wait and see approach.Is the
native protocol specification and drivers still in DataStax's git?
If it's going to be the "standard" protocol, then it really should be in
apache's repo. That's my bias opinion.

Unless a cassandra driver is using the native protocol, it's going to have
a very short life going forward.

it is using thrift. I've updated the project page to state that info.
