Github user vanzin commented on the issue: https://github.com/apache/spark/pull/22511 LGTM. I went back and took a look at the related changes, and agree with Imran that this is basically the same thing that 2.3 did; so no perf regression, just higher memory usage than in the mmap case (which didn't exist before anyway).
