big java solutions

There is a big data project, you know the problem area (problem domain), you know what infrastructure to use, and maybe even decide which framework to use to process all of this data, but one decision has been delayed: which language should I choose? (or perhaps more specifically, the question is, what language should I force all my developers and data scientists to use?) This question will not be postponed for too long, but will be decided sooner or

Summary: When it comes to dealing with large-scale data, R, Python, Scala, and Java basically meet your requirements. There is a big data project, you know the problem area (problem domain), you know what infrastructure to use, and maybe even decide which framework to use to process all of this data, but one decision has been delayed: which language should I choose?

situations:One is a memory overflow, because each request has to load a file size of memory even more, because the Java wrapper will produce a lot of other memory overhead, if the use of binary will produce less, and in the process through the input and output stream will experience several memory copies, Of course, if you have a similar nginx like the middleware, then you can send out through the send_file mode, but if you want to use the program to
