From reading it, I'm not really sure if it's eventually consistent or not.

> Replicas then update cache pages in the shared buffers. This ensures eventual consistency for read replicas within the same region as your database.

> Data Consistency: Reading data from a single source ensures data consistency. This addresses a common challenge in traditional read replicas where there might be a replication lag.

> Resource Customization: Neon allows you to allocate different CPU and memory resources for each replica.

So there is a single source of data, but can have different CPU and memory and has eventual consistency in the same region?
