basically they separate the compute and storage into different components, where the traditional PG use both compute and storage at the same server.

because of this separation, the compute (e.q SQL parsing, etc) can be scaled independently and the storage can also do the same, which for example use AWS S3

so if your SQL query is CPU heavy, then Neon can just add more "compute" nodes while the "storage" cluster remain the same

to me, this is similar to what the usual microservice where you have a API service and DB. the difference is Neon is purposely running DB on top of that structure

So how is this distributed Postgres still an ACID-compliant database? If you allow multiple nodes to query the same data this likely is just Trino/an OLAP-tool using Postgres syntax? Or did they rebuild Postgres and not upstream anything?

They keep using the core Postgre while they touch the storage layer to works with S3. Can try ro read more here https://jack-vanlightly.com/analyses/2023/11/15/neon-serverl...
