The This talk is for everyone looking for an overall introduction to Apache Flink and the big ideas that make it special. Along the way, we'll explain what use cases can be tackled, show you how to choose an API, and share the resources we've found most helpful for getting started. In particular, we'll cover the key organizing principles that make it possible for Flink to deliver high performance, robust stream processing, at scale, and we will answer questions like these:

Is Flink appropriate for my use case?
What does it mean that Flink unifies batch and stream processing?
What does "exactly once" mean, and why should I care?
How do I choose between the DataStream, Flink SQL, and Stateful Functions APIs?
What are Watermarks?
What are the best resources for getting started quickly?

Thank you for the video. A quick honest feedback.

Presentation is disorienting.
I would like to hear it like:

* What Flink is
* Who uses it? why? (not generic, specific)
* What you are introducing in this video, (story, expectation)
* Demo
* show requirements
* show the solution
* show what's implemented
* explain what you do the things you do
* Conclude
* What if you don't use flink (flink vs hard way to do it)

I am confused. How is this different from Kafka Streams and KTable?

[avalagum]

What's the disadvantage of solving this problem with Kafka stream?

Where can I find the code we saw in this presentation?

[parth]

I installed flink but can not access the UI.

Flink is still more like a concept, a set of libraries, classes for writing software than ready-to-use software. This software is still very feature-poor. It can change drastically in subsequent versions. Documentation is poor in examples and unclear.
Still a long way to go.

Great session.!!
If we are sending the records to Kafka that having inheritance nature i.e. with parent and child class.
Class Vehicle {
}

Class Car extends{
//Some code
}
For this, how can we generate deserialisation schema in flink?
