Apache Flink

Hi, I'm a novice developer interested in quant trading, I was looking at two sigma's GitHub and saw code for Scala and Apache spark.  I've never worked with Apache data products so I'd thought I'd learn it by creating a small Dockerized app that uses Scala 3, Flink, and some financial data I already have in csv or pandas dataframe.  The app would process the data in some way by adding indicators or running it through an ml function. Scala 3 and docker are a must.  Does my project make sense? Am I using the right products?

Scala isn’t really a first class citizen anymore in Flink

But you can definitely use Scala to write your Flink application, but you should use the Flink Java APIs
