cheapest DB to implement for my severless marketing site?

I have this data that was written to a PSQL database. And now its also in text form.

​

There are two tables:

1. simulation inputs
2. summary results of the simulation for each data point

They can be joined on an 'id'

​

So basically, 270k rows x 2. Each entry (in each table) has like 5 attributes.

​

Do I have to do DynamoDB for severless? How would that work? Thanks, just trying to figure this out. I guess lambda can run psycopg?
