A Sample Project (fraud detection) for studying Kafka and Flink

My Goals

The sample code I copied/modified based on afedulov/fraud-detection-demo.

• run/debug with intellij idea.
• understand pros and cons between flink streaming and (spark streaming & kafka streaming).
• help me to understand flink infrastructure and design idea.

How to Run/Debug with Intellij Idea

As described in My Goals, it's critical to have a local runnable environment to reach my goals.

2. docker-compose run -f docker-compose.yaml.
3. open project with intellij idea.
   • follow prompt window to import found projects. (Optional, execute Invalidate Caches... when experience build issue.)
   • run npm install under webapp/ to install ui dependencies.
4. switch to .run, and open 3 pre-saved debug/run configurations.
5. start job/app/ui with debug/run tool.

NOTE, After following step #3, the run/debug configuration will look like this:
