Speakers' information:

Mika Naylor, Developer, Crate

Mika is a developer at (, working primarily with infrastructure, Kubernetes
and Docker. She is also a maintainer of Black, a python code formatter project.
Outside of software she enjoys hardware tinkering, monochromatic colour palletes and
reading on cybernetics, solarpunk, and the politics of technology.

Title of the Talk:
Local Weather Visualisation with IoT, Kafka and CrateDB (

Ever wanted to build your own weather data service? In this talk Mika will talk about
how - from building your own IoT enabled weather station - to setting up
weather data ingestion pipelines with Kafka and CrateDB, to creating a simple API
using Flask for visualisation.


Robin Moffatt, Developer Advocate, Confluent

Robin is a Developer Advocate at Confluent, the company founded by the creators of Apache Kafka, as well as an Oracle ACE Director and Developer Champion. His career has always involved data, from the old worlds of COBOL and DB2, through the worlds of Oracle and Hadoop, and into the current world with Kafka. His particular interests are analytics, systems architecture, performance testing and optimization. He blogs at and (and previously ) and can be found tweeting grumpy geek thoughts as @rmoff. Outside of work he enjoys drinking good beer and eating fried breakfasts, although generally not at the same time.

Title of the Talk:
Apache Kafka and KSQL in Action : Let’s Build a Streaming Data Pipeline!

Have you ever thought that you needed to be a programmer to do stream processing and build streaming data pipelines? Think again!

Companies new and old are all recognising the importance of a low-latency, scalable, fault-tolerant data backbone, in the form of the Apache Kafka streaming platform. With Kafka, developers can integrate multiple sources and systems, which enables low latency analytics, event driven architectures and the population of multiple downstream systems. These data pipelines can be built using configuration alone.

In this talk, we’ll see how easy it is to stream data from a database such as Oracle into Kafka using the Kafka Connect API. In addition, we’ll use KSQL to filter, aggregate and join it to other data, and then stream this from Kafka out into multiple targets such as Elasticsearch and MySQL. All of this can be accomplished without a single line of code!

Why should Java geeks have all the fun?
