Subject Re: java vs scala for Apache Spark - is there a performance difference ?
Date Mon, 29 Oct 2018 20:57:56 GMT
did not see anything, but curious if you find something.

I think one of the big benefit of using Java, for data engineering in the context of  Spark,
is that you do not have to train a lot of your team to Scala. Now if you want to do data science,
Java is probably not the best tool yet...
