Learn by Example: Apache Flink

Flink is a stream processing technology with added capability to do lots of other things like batch processing, graph algorithms, machine learning etc. Using Flink you can build applications which need you to be highly responsive to the latest data such as monitoring spikes in payment gateway failures or triggering trades based on live stock price movements.

This course has 30 Solved Examples on building Flink Applications for both Streaming and Batch Processing
