What is Aura Serverless V1's Consistency Level?

Question

We've are using Aurora Serverless V1, using PostgreSQL 11, and are running into some issues that *might* be caused by eventually consistent reads, but I'm having a hard time finding documentation for Aurora Serverless V1 specifically

By default, are queries against an Aurora Serverless v1 cluster eventually or strongly consistent? And is there a way to force a specific consistency level for a given query, or perhaps cluster?

Answer

If you are using Aurora Serverless v1, just one single DB instance is running in the backend, so you should always have read-after-write consistency. In Aurora Serverless v2, you can have additional instances that are readers, and you only have strong read-after-write consistency in the writer, and the readers have eventual consistency.

Can you explain a little more why do you think you're having eventually consistent reads? It's challenging to provide a good answer without enough context.
