The docs make no mention of read-only at all (unlike redis)
There’s also no mention of the replica-read-only config option on https://www.dragonflydb.io/docs/managing-dragonfly/flags
I need writable replicas, so wondering if they already are or if there’s a config option for that.
we do not support master-master replication
so they are always read only
neither does redis 
I have very loose data consistency requirements for a few specific keys that are also per-system (each system has a local replica of the main db)
so for performance reasons I wrote those directly to the replica which is on localhost
ig I could just spin up an extra db for those few keys
ok, so you do not want master-maser, you just want a writeable storage in a process. Yeah, unfortunately we do not support this either though if we ever support true in-process multi-tenency, it will be supported there
