How to check if AWS secrets keys are being used or not? If not, I can delete them

I have used pyarrow and fastparquet to put a data frame in a buffer and then create a parquet file of it. But everytime I run my code the output is null. Any guesses?

Or any command needs to be added to the pipeline of ci/cd?

Lol your dob, are you a vampire ?

Can I ask springboot related questions also here?
