Hi All,


Henning, thank you for introducing me.

As announced yesterday I have been working a Cassandra DB driver for Sip-Router and today I have committed the new module db_cassandra into the master branch.

This module offers a DB interface and can be used by other modules to perform DB operations instead of db_mysql for example.
Because Cassandra is a NoSQL storage system, it is not possible to run all kind of queries on it and this is the reason why the module has some limitations.
It is especially suited for applications that store large data or that require data distribution, redundancy or replication. One usage example is a distributed location system in a platform that has a cluster of SIP Router servers, with more proxies and registration servers accesing the same location database. This was actually the main usage we had in mind when implementing the module. It has been tested with usrloc and auth_db modules, but it can also be used with other modules that have simmilar queries. You can read more about this in the README file http://sip-router.org/docbook/sip-router/branch/master/modules/db_cassandra/db_cassandra.html.

Inside the module you can find a configuration file example that modifies the default configuration file to enable a location service with a Cassandra backend. If you have a Cassandra installation, it should be very easy to test it.

We hope you find this module useful and are glad to receive any feedback, comments about it.

Thanks and regards,
Anca

Hello all,

I'm happy to announce a new developer for the project: Anca Vamanu.
Welcome to the development team!

Anca joined 1&1 last year and worked since then on several internal modules 
and also many important bug fixes for our kamailio server setup. She is a 
experienced C and C++ developer and contributed in the past a lot to OpenSER 
and other VoIP projects.

One interesting work she just finished and that we also like to contribute to 
the community is a db_cassandra module, providing access to this NoSQL 
database [1] from kamailio. She will take over the maintenance of this module 
and also work on improving other parts of the server.

Best regards,

Henning
