Day 5 / Apr 25 (Mon)¶

Welcome to Week 9¶

Coming up are 2 days (Mon and Tue) to develop a solid foundation of Kafka Streams with Scala.

Wed and Thu are conference days.

On Fri, half a day for Kafka Connect and another half for Akka Streams. Just a tiny bit as they are considered information-only.

Morning Exercises¶

Algorithmic Thinking¶

1. [2020-10-21] Challenge #386 [Intermediate] Partition counts

Object-Oriented Programming¶

Define a Room class that should do the following:

1. A room has a name and capacity
   • capacity = the maximum number of people that can enter a room
2. A person can enter a room (only when there is still free space)
3. A person can leave a room
4. A room can report the number of people inside (who entered)

Write tests and publish to Github.
