[SR-Users] redis template config for topos module

[Patrick Karton]

we are using topos with redis backend.

at first we started  using topos with db_text but we noticed too much retransmission on kamailio so we switched to redis and retransmission disappeared (80 caps 5000 concurrent calls with redis).

now above 120 caps retransmission comes time to time even if acceptable.


We use HA with 2 kamailio so we need to synchronize sessions through redis. of course there is also DMQ i think.


have you some numbers results or suggestion to go with redis or DMQ for sessions Synchronization ?

Thanks.

Hello,



we are using topos and redis in a few customer installations. So far we did not had the necessitity to tune it to certain performance requirements from Kamailio side. It worked out of the box. I am of course interested what other people can share in this regards.



For the dialog module it’s another question, as one usually needs to use the db_redis module with dialog database backend. When using a local redis server, my suggestion would be to always skip the database and just use the in-memory mode of dialog module in the first place, as there are no benefits in this setup. Of course for a remote redis server if could be benefitial in some scenarios, like restart of dialog module.



Cheers,



Henning
