This was a fun Drupal 8 Commerce project that I had the change to work on. In this project I set up a REST API that consumed Drupal Commerce orders. There was also much more back-office functionality that was heavy on the PHP memory. E.g. custom PDF generation, shipping automation, order report generation.
There were many challenges with this project so it was always good to be informed and to plan ahead for the future months. I think this was one of the critical aspects of developing the whole system. Going from a few hundred orders a day to a few thousand orders a day makes a big difference. Planning for this and load testing the system was critical.
The end goal was to consume 300k orders a month so it was very crucial to plan for this in many ways. Not only were server resources needed but also to plan for the database. Orders for this project had many fields so I was working with a lot of information stored here. The database would start to grow very fast.
