Scheduled Job to write data to CSV then delete that data

Hi, I'm new to MySQL 8, although I used a couple of other RDBMS a few years ago.

I have an app that is writing performance data to a few tables on a very regular basis. I need to get/extract the perf data out of a couple of tables in MySQL on a regular schedule into CSV files (e.g. every 10 minutes). I want to either mark or delete that data after an extract has run. The data is time sensitive so I want to avoid duplicates in my extract or gaps where I missed stuff. Perhaps a daily 'Purge' should also run on marked records.

Looking for advice on the best way to acheive the above.

General questions:
Are SQL queries best with MySQL scheduled tasks, or is it better to script this?
Do I need to be careful about record locking as the tables have data coming in regularly?
General hints and tips, or anyone have a similar example to share?

Much appreciated,
Bob.
