Don't trust Kafka Connect with your secrets
Open source is great but sometimes it misses the mark for security at enterprise levels. Take Kafka Connect, I’ve built a few connectors in my time and prior to its introduction to Apache Kafka back in 2017 I used other hand cranked pieces of software and security was always a primary concern. One feature that will quickly put a blocker on your project being successful is not reaching production. There’s a number of reasons for this but high up, usually top, is security.
