BigData / Apache StreamPark Interview questions
What is StreamPark Core?
StreamPark Core is the development-framework half of the project. It's positioned squarely as a coding tool rather than a web platform, and it follows a "convention over configuration" philosophy: project layout, configuration files, and startup parameters follow a standard shape so developers spend less time on setup.
Two things make it useful day to day. First, it exposes a RuntimeContext that wraps common environment setup for a Flink or Spark job. Second, it ships a library of out-of-the-box connectors, so pulling from Kafka or writing to a sink doesn't mean hand-rolling boilerplate each time.
Core also unifies the DataStream API and Flink SQL API under one set of extension methods, so a project can mix both styles without maintaining two separate mental models.
