Tracing is an essential part of api-platform as a service. A year ago we have started with Zipkin and later moved on to Jeager (by Uber) and nobody knew at that time, that even this wouldn't be not enough for our consumers (over 5 MIL tracing records per day).
After less than one year in production we had to change our architecture and replaced almost everything of it with a custom-built solutions.
We will share our story from the very beginning to the present day about how we made it possible, our struggling through difficulties, ideas we had & original technical solutions.
