Completing the data lifecycle is often harder than originally expected: Deleting data can cost sometimes way more than inserting it in the first place. MySQL Partitions can offer a way out. We have an earlier post on the subject.

A sample table, and a problem statement

Let’s define a kind of log table, to which data is added with an auto_increment id value and some data.

#! /usr/bin/env python3

from time import sleep
