InfluxDB

Imo the tooling has to become way more user friendly. The Scala community has picked up on this and made Scala-CLI the official running tool for Scala. It's a great tool for single module projects and makes everything from adding dependencies to building fat jars very easy, also the runner comes as a native image. The reason I'm mentioning is because sometimes we forget how hard it can be as a beginner, especially when younger people are used to simpler CLIs from newer languages.
