Planning to configure one DF master with 3 replicas. One should never be promoted to master. Is there a possibility with Dragonfly to tell Sentinel this node has a replica/slave priority = 0?
Dragonfly does not communicate with sentinel directly, it just supports the operations that sentinel issues. Please check with redis-sentinel documentation if it is possible to configure it in such way
Thank you, but this setting is a REDIS/DRAGONFLY setting and not a REDS-SENTINEL setting. If you add replicas to Dragonfly, dragonfly set the priority to default (“slave-priority” “100”). If you have a replica far away e.g. behind a VPN its not a good idea to promote it to master. Or if you have 5 dragonfly Server, 4 Server with a lot of RAM and CPU and one Server with less power, it would be nice to give the slowest member a lower priority or in this case a priority = 0.
