Odd one this, and one that took me a little while to debug. I recently set up a Confluent/Kafka data pipeline with transformations being handled by KSQL and data being produced by an application written in Go. As part of the test process I persisted data using a MongoDB Sink connector. The command line producers had no problems and producing a large file would persist the expected data to MongoDB. However, I ran into issues when producing from Golang, I would notice that somewhere between 7% and 12% of the messages were being persisted to MongoDB, the others were lost somewhere in the processing.

If you've ever written a test in golang, chances are you've used the testify package to make writing tests a breeze. An immensely useful extension of that is the mockery package, which gives you the ability to autogenerate testify mocks for interfaces with ease.

I recently moved into some co-working space and I immediately had issues with the internet connection. My connection would be intermittent and would frequently drop; sometimes I had hours of uninterrupted connectivy, at other times it wouldn't last more than a few seconds without dropping completely. I had no issues with any other wifi network at home, in offices or in public.

There's a bug with Eloquent's firstOrCreate() function where it doesn't work with the $casts attribute on the model; it will always either insert a new instance into the database or give a MySQL duplicate entry error.
