I think the main difference is that by making replicas writable you lose the ability to have redis throw an error like Postgres does when you try to write to a replica. The upside is that you can write to replicas when you don’t need a global write without rerouting the request somewhere else, the downside is that your app has to have that knowledge about which one to use in which situations. It’s definitely an interesting set of trade offs for the two use cases!
