The best way to have fewer problems with data is not to have the data

I am a strong believer that more data is not the merrier. Sustainability, costs, complexity, compliance. There are different reasons why you should minimize the data you collect. I (sort of) love tuning a MySQL database, but the best way to optimize IOPS on RDS MySQL is not to save the data in the first place. I had a nice chat with the team at Datamin a few months ago on the topic. Take a look!
