Andreas Granig from Sipwise has pushed recently a new module for Kamailio, respectively db_redis, which implements database connector API. The readme of the module can be found at:

Practically it should be possible to use db_redis module instead of any other database connector module, such as db_mysql or db_postgres., for modules like usrloc, auth_db, a.s.o.

Redis is know to be very fast key-value storage system, with very good replication and redundancy option, already popular in Kamailio ecosystem  Рsee also ndb_redis or topos_redis modules.

Andreas is testing the performances of Kamailio with db_redis versus other popular database connectors, the results are very promising in a boost of performances.

As a matter of fact, Andreas will give a presentation about this topic at Kamailio World Conference 2018, a session you should not miss if scalability is important for your VoIP/RTC service! See you there!

Thanks for flying Kamailio!
