🔗 Once again processing 11 million rows, now in seconds

Two weeks ago I went on an optimization spree when a PHP script had to process 11 million database-stored events. My initial code processed around 30 events per second, which meant the whole operation would take around 4 days to complete. In my last post, I managed to get that number up to 50k events per second, resulting in only a couple of minutes of runtime.

I knew there was still room for improvement, though, and so, the journey began again.
