Is Amazon’s new MongoDB-compatible DBMS really PostgreSQL under the covers? ↦
This is a nice rundown of the technical clues indicating that DocumentDB might be powered by Postgres.
PostgreSQL isn’t the only DBMS that scales writes vertically and reads horizontally via replication, but when you add this all up, especially some of the specific limitations, I think it makes a pretty compelling argument that PostgreSQL is the engine powering AWS DocumentDB.

Has anyone written up a comparison of the new AWS DocumentDB to Azure’s CosmosDB and even to the existing AWS DynamoDB? Things like cost, use-cases, etc.? Coincidentally, the new DocumentDB at face value sounds a whole lot like Azure’s CosmosDB, which was originally named DocumentDB!

Hmm, good question! 🤔
I don’t know of any comparisons out there, but I’d absolutely love to read (and share) one if someone were to do that work… 😉
I agree with you that these seem like very similar offerings. Funny that they used to even share the name!
