> Of course, this is sometimes abused and taken to extremes in a microservices architecture where each service has their own database and you end up with nastiness like data duplication and distributed locking.

Not to mention the difficulty in maintaining referential integrity with all of that duplicated data. There are various workarounds, but at that point it feels very much like we’re recreating a shared DB, but shittily, and netting zero benefits.
