London Scala December 2018 Meetup
- December 10, 2018
Join us on Monday, December 10th for the year-end meeting of the London Scala User Group at Code Node. The event will feature presentations from 47 Degrees’ Diego Alonso, as well as Lindsey Dew and Omnia Ibrahim from Deliveroo covering functional streams in FS2 and Kafka.
Functional Reactive Programming with FS2
- Diego Alonso
- 47 degrees
Functional Reactive Programming is an approach to writing programs. FRP uses signals, which represent a mutable value time-line of a value, and signal transformations as its basic blocks. ‘fs2’ is a functional streaming library for Scala.
This talk explores the key concepts of both FRP and ‘fs2’, how they relate to each other, whether we can write an FRP system on top of ‘fs2’, and what ideas from FRP can be used to guide future development of ‘fs2’.
Introduction to Kafka streaming
- Lindsey Dew & Omnia Ibrahim
The last few years we’ve witnessed the rise of data-driven projects, with Apache Kafka leading the charge for streaming big volumes of data.
In this session, Omnia and Lindsey will introduce you to Kafka Streams. They will be sharing with you Scala code examples, demonstrations of use-cases they have at Deliveroo, the problems they faced, how they solved them, and the lessons they’ve learned.
