In the company, we're introducing Mongodb.
Our is tech stack is mostly gRPC services running on Kubernetes. So we decided to build an Event Sourcing system to track down all our transactions across the microservices interactions.
We decided to store the events into a Mongodb. At the beginning we got stuck trying to perform operations on the tables, because we need authenticate before that. It took a while to figure it out. A colleague and I got stuck for hours (working in parallel). We realized we had the same problem in the next stand up meeting. All the team agreed that some sort of example and reference to the actual Authentication documentations might come in handy.
I found this on stackoverflow and the accepted solution did the trick.
