That depends. You don’t need quorum writes with traditional Postgres or MySQL HA setups. In most cases, writes go to a single primary, and replication to standbys is asynchronous or semi-synchronous, depending on your tolerance for potential data loss.
It’s all about finding the right balance. With modern vertically scalable hardware and fast SSDs, a single-node setup can handle quite a lot of load before hitting real limits with a failover setups.
