Flink Checkpointing Demo
Flink Checkpointing Demo is a free, interactive learning demo from the Data connectivity and integration course on Lykke. It helps you build intuition for Apache Flink, Foundry Streams, Hot and Cold Storage, Exactly-Once Semantics. Play with it directly in your browser — it features 2 sliders and a live visual canvas. This demo lives in the “Real-time Data Processing with Flink” section of the course.
How to use this demo
- Drag the “Stream Speed” slider to change the inputs and watch the result update live.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Apache Flink
- Foundry Streams
- Hot and Cold Storage
- Exactly-Once Semantics
- Streaming Profiles
Frequently asked questions
What does the Flink Checkpointing Demo demo do?
Flink is processing unbounded data streams and maintaining an internal "Managed State" (Sum). Flink Checkpointing Demo lets you explore this hands-on instead of only reading about it.
What Data connectivity and integration concept does Flink Checkpointing Demo teach?
Deep dive into Foundry's streaming architecture, powered by Apache Flink, for low-latency data processing. It focuses on Apache Flink, Foundry Streams, Hot and Cold Storage, Exactly-Once Semantics, Streaming Profiles from the “Real-time Data Processing with Flink” section.
What can I control in Flink Checkpointing Demo?
The “Stream Speed” slider change the key inputs. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Flink Checkpointing Demo fit into the Data connectivity and integration course?
This course provides a comprehensive deep dive into Palantir Foundry's data connectivity and integration suite, which transcends traditional ETL/ELT methodologies. Students will explore how to build robust, scalable dat… This demo is the interactive piece for the “Real-time Data Processing with Flink” section.

What will I understand better after using Flink Checkpointing Demo?
You'll build intuition for Apache Flink, Foundry Streams, Hot and Cold Storage, Exactly-Once Semantics, Streaming Profiles — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Data connectivity and integration alone.
