Exploring Dynamic Sink Routing in Apache Flink via DemultiplexingSink

Last year, I wrote a blog post discussing ideas on how to support use-cases in Apache Flink that required dynamically resolving (and potentially creating) sinks at runtime based on the incoming data. While this solution was fairly practical, it was written against older APIs as opposed leveraging the new Unified

Reflections on Current 2025: Streaming, AI, Beignets, and The Buffalo Bills?

As the mental (and possibly physical) hangover begins to wear off, I figured I’d take a moment to reflect on my recent trip to Confluent’s 2025 Current conference, conveniently held right here in my home state of Louisiana. It was a week filled with brilliant people, incredible sessions,

Incremental Optimization in Apache Flink ... with AI

While performance always matters, streaming pipelines are where it can matter a lot. Concepts like Big O notation that you may have repressed from your days learning computer science can come back to bite you if neglected (I’m looking at you, quadruply nested loops). Often, the most minimal of

Putting the Fun in C# Local Functions

Many popular languages support the use of local functions [https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/local-functions] and in C# 7, support for them was announced with relatively little fanfare. As someone that would consider themselves a C# power-user, I seldom took advantage of the feature until I
