A new module is now part of the GIT master branch (planned to be released as v4.2.0 sometime next year). The module is named ndb_cassandra and it is offers an API to Kamailio’s configuration file for setting and getting values from a Cassandra database system.
Contributed by a recently added developer, Luis Martin Gil, the new features will provide full flexibility to the configuration file to access Cassandra records. There is another Cassandra related module, db_cassandra, which is a database driver module, that can be used instead of Mysql or Postgres SQL connectors for modules such as auth_db, usrloc, etc.
The readme of the new module can be found online at:
