.NET for Apache Spark – VSCode with Docker on Linux and df.Collect()

Overview

My last article explained, how a .NET for Apache Spark project can be debugged in Visual Studio 2019 under Windows. I have also mentioned some limitation at the end of the article.
In this article I will extend the project a bit and demonstrate the aforementioned limitation using version 0.8.0 of my docker image for .NET for Apache Spark.
Furthermore, I will show a possible workaround that can be used, if you are running Docker and Visual Studio Code under Linux (Ubuntu 18.04).

The extended application

In order to demonstrate the issue, I have … more

Real-time data processing pipeline – Part 2 – OSC to ActiveMQ

Welcome back to the second part of my series, showcasing a real-time data processing pipeline!
In part 1, I explored visual real-time sensor data simulation, as the entry point into our pipeline.
Now it’s time to find out, how we can get the generated data into Apache ActiveMQ, by transferring it via the OSC protocol.

Apache ActiveMQ™ is the most popular open source, multi-protocol, Java-based messaging server. It supports a variety of Cross Language Clients and Protocols, and therefore makes it an excellent choice for our pipeline.

Get ActiveMQ up and running

I won’t … more
