Presentation explains Reactive architecture based on Akka and Kafka technologies. Presentation includes GitHub demo that implements corresponding architecture

1. Connecting AKKA with
Oracle Event hub
AKKA Actors Event Hub AKKA Streams

2. What is Oracle Event Hub?

3. We all heard about Kafka. But!
• Is Kafka another Service Bus?
• We can use Kafka as a Big Data Lake?
• Can we achieve the same thing with JMS
Topic and the Database?

4. Architecture paradigm shift
Don’t join tables. Join events!:
• Real time ETL
• Fast data processing
• Think asynchronous
• You get it when we got it!
• Your data Is safe with us

5. How Kafka Works?
• Many to Many model
• Every Topic is replicated
• Your keys are safe in our Partition
• Delivery guaranty
• Poll consumers
• Producer can connect to
anything
• Consumer can connect to
anything

6. Real life problem - we are still sending files

7. First solution

8. Better solution – Do it in Parallel!

9. Well than can we use AKKA. But why?
8
• Can be Kafka Producer or Consumer
• We love working in parallel!
• We love Actors!

10. AKKA Streams

11. So a better solution architecture can look like…

12. Huston now we have a problem!

13. What a relief

Backpressure regulation
Throttling

14. Now the demo
