It is not possible to specify multiple redis servers

Hi,

we are using osprofiler with redis as backend.
Redis is a three node cluster with sentinel installed.

The redis:// or redissentinel:// url only work with one server.
Is it possible to specify multiple servers?

We are also using gnocchi with redis. There you can specify the fallbacks with the url:
redis_url = redis://172.20.20.16:26379?sentinel=master01&sentinel_fallback=172.20.20.17:26379&sentinel_fallback=172.20.20.34:26379&db=0

This bug is somewhat related to https://bugs.launchpad.net/osprofiler/+bug/1811372
