Because we don’t want everything to fall over when one machine goes down we need at least 3 machines (for raft). So if our traditional db would have 500 GB of data we now need 3 machines with 500 GB of ram running at all times. That is an epic waste of money. Millions per year to run ? And you could store it in a db for a couple of dollars.
