I see in https://github.com/getsentry/sentry/issues/3745 that redis clusters are not supported, however, a quick glance at the source code https://github.com/getsentry/sentry/blob/master/src/sentry/utils/redis.py suggests that rb is in the process of being replaced by native redis clusters.
How do I use the native redis clusters in my setup? Are there any clusters which still require a rb cluster?
