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 
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 

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,
