Our final LSUG of 2018 will be a festive one, with the tinsel exchanged for shiny, sparkly functional streams in FS2 and Kafka. Don't miss it!
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'.
Diego is a Scala developer at 47 Degrees, where he writes backend applications using functional libraries like Cats and Cats-Effect, Fs2, Doobie, Http4s, or Circe. Diego has been writing declarative code for almost 10 years, using Scala, Haskell, and Prolog.
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.
Lindsey is a Data Engineer working at Deliveroo and is passionate about developing processes and systems to drive data-driven decisions across an organisation. She previously worked on the data technology team at the Guardian.
Omnia is a Data Engineer at Deliveroo. Previously she developed her passion about data driven projects while working as senior consultant at Thoughtworks.
