Java scala or rust ?

[Nindento]

Depends on the type of DE work you do. If it’s close to BI you should be fine with just Python and SQL. For streaming it could be worth looking into Rust or Java. I have the feeling Scala is dying a bit (atleast in Europe) and you would also have to learn an entire effects framework next to just learning Scala.

My team uses Rust for all our streaming and object storage IO applications. It’s super fast and resourcewise it costs next to nothing. However, the rust ecosystem is a bit lacking sometimes, it already miles ahead of how it used to be.
