## What it is
A collection of scripts, Docker Compose setups, and sample code supporting Confluent's demos, talks, and blogs about Apache Kafka and its ecosystem. It covers streaming pipelines, CDC with Debezium, ksqlDB, Kafka Connect, and event-driven applications, though not all examples are kept up to date.

## Use cases
- learn apache kafka with runnable examples
- demo a streaming ETL pipeline from mysql to elasticsearch
- try debezium change data capture with ksqlDB
- build a demo event-driven microservices workshop
- stream data from postgres to kafka and beyond
- set up a kafka demo environment with docker compose
- explore kafka connect connector examples

## When to choose
- you want hands-on, copy-paste demo environments for Kafka, ksqlDB, and Kafka Connect
- you are preparing a talk, workshop, or blog post about Confluent Platform
- you want to experiment with CDC pipelines using Debezium and various databases
- you prefer learning from ad-hoc samples rather than QA'd tutorials

## When to avoid
- you need production-ready, maintained, QA'd code - use confluentinc/tutorials or confluentinc/examples instead
- you need a supported library or SDK to build an application
- you cannot spare 8GB of memory for Docker-based demo stacks
- you need guaranteed up-to-date examples - the repo explicitly says not all are kept current
