Connecting to a Cassandra database

[Arun_Persaud]

Hi

does a labview library exists that can talk directly to a Cassandra database? If so, which version of cassandra are supported?

Thanks

Arun

I would start with the ODBC drivers, and then use the Database Connectivity Toolkit or something else like LabSQL.

Thanks for the tips. I played around a bit and managed to connect to cassandra directly using the binary protocol and CQL. Since mostly do write I probably just use that.

Hi

I ended up implementing part of the cassandra binary protocol in labview. If anyone is interested the files can be found here:

https://bitbucket.org/berkeleylab/atap-labview-cassandra-driver

It's by far not a complete implementation, but it allows me to do what I need.I'm happy to add more functionallity to it or accept pull request 😉

Hello

It is an old subject but I search to connect to a cassandra database with autentication... i saw in your release that it is not supported: was it impossible?

Best regards.

Hi

no, this should be possible, we just didn't need it. We have a cassandra node behind a firewall, which is set up without authentication and then we have another node outside the firewall with authentication. In our setup LabVIEW only reads and writes to the node that doesn't need authentication.
