Getting Started as a Kafka Developer
Once you’ve decided on a language to focus on, it’s time to start filling those knowledge gaps. Don’t be discouraged by this step. We all have knowledge gaps, and filling them can be very rewarding. First, you’ll want to make sure you have a good understanding of Kafka basics. Fortunately, there are many resources to help you with this. A web search will turn up many great books and other resources. And, of course, Confluent Developer offers interactive courses ranging from introductory (Apache Kafka 101) to advanced (Kafka Internals), full documentation, and other content to help you get started.

Problems with the set-up
Spend some time on https://developer.confluent.io , especially https://developer.confluent.io/get-started/java/ and look at https://github.com/confluentinc/examples . Those will give really practical examples for how to set up your configs and start consuming

Kafka to fetch data from another microservices
Kafka streams is a Java library built on the producer/consumer APIs designed to create event-driven microservices on top of Kafka. In general, I recommend exploring https://developer.confluent.io to learn more

A few starter questions: What is a good setup for learning? Is Confluent platform ok?
Are you getting ahead of yourself to use Kafka Connect? No, definitely not! Kafka Connect is part of Apache Kafka so you're just learning more Kafka :) The connector plugins vary in author and licence. There is a mixture of vendor and community-written plugins. The Twitter one you found is great - I've used it in the past several times for projects. If you want another set of code to look at using it there is this repo here and related blog
should I be reading a different material for a first Kafka project and working with a different kind of setup? Now, I can't be unbiased on this one ;) One of the things we're doing with Confluent Developer is to try and create a resource for people to learn Kafka from the ground up, whether they ultimately decide to pursue it on Confluent or not. The fundamentals of Kafka that you'll be learning are going to be as applicable whether you're using Apache Kafka self-managed, or Confluent, or AWS' MSK, or whatever else. Personally I'd this stage I'd use whatever setup you find easiest and least friction to your learning journey. As u/louisvell mentioned, /u/stephanemaarek's courses on Udemy are also very popular, if you wanted a "second opinion" on how to approach learning Kafka.

Ask HN: What are your “scratch own itch” projects?
Right now: kcctl [1], a command-line client for Kafka Connect. Using the REST API just became to unwieldy when demoing Debezium. Quite a while ago, MapStruct [2], a code generator for type-safe mapper classes for converting POJOs (Java object) between object hierarchies which are similar but not quite the same. It was born after realizing that significant time in an enterprise application I was working on back in the day was spent executing reflection-based mapping code.
