Which database to choose (and how to further configure it) solely for the fastest possible inserts of new records?

Question

SQL

Hello! The essence of the situation:
Python application writes data to the database. And that's pretty much all it does.
So far, no reading is required. Data integrity must be guaranteed. The number of requests per second is not constant - it can be 1 request / sec, or maybe 1000 / sec.

Answer 1

First we use Read uncommitted.
We do not use indexes.
There will be problems:
We write to a file, and from it we slowly transfer it to the database.
Maybe store everything in files?
What data and what for do you need?

Answer 2

mysql MyISAM was made for this. Especially if without indexes.
