Spark on OpenSlava 2017

I will show how you can leverage the containers and run the Spark cluster in PaaS, namely OpenShift and Kubernetes. For demonstration purposes, I'll be demoing the Blockchain analysis in Jupyter notebook using the Spark cluster running in OpenShift, everything dockerized. I am out of buzzwords.

Apache Spark on Kubernetes 2018

Have you ever wondered how to implement your own operator pattern for you service X in Kubernetes? You can learn this in this session and see an example of open-source project that does spawn Apache Spark clusters on Kubernetes and OpenShift following the pattern. You will leave this talk with a better understanding of how spark-on-k8s native scheduling mechanism can be leveraged and how you can wrap your own service into operator pattern not only in Go lang but also in Java. Let's make the data science more scalable in a cloud native fashion.

Blockchain Analysis @ DevConf 18

In this presentation I showed a simple way of leveraging Spark's GraphX and GraphFrames for analyzing the transaction graph of Bitcoin transactions. Real data was used.

Reactive Programming @ DevConf 16

The Reactive Extensions (Rx) is a tool for composing asynchronous and event-based programs using observable sequences. It's very powerful technique to avoid callback hell and it can be used both on the server side as well as for designing the user interfaces. It leverages the concepts from functional programming such as composable monadic functors, immutable state, etc. There are libraries for Rx to almost all modern languages (Java, .Net, JavaScript, C++, Scala, Android sdk, etc.) and the presentation will show the examples in multiple languages.

Writing an internal DSL language in Scala

Have you ever wanted to write your own programming language? Why not to start with much simpler task - writing some domain specific language. Since the Scala programming language is a great fit for creating internal DSL, we will utilize its functional nature and implicit conversions, and together we will create a fluent API in form of a DSL. Scala noob? No worries! No previous Scala experience is needed, all the techniques will be explained during the workshop. It’ll be piece of cake if you know any modern programming language.
