HyukjinKwon commented on issue #23760: [SPARK-26762][SQL][R] Arrow optimization for conversion from Spark DataFrame to R DataFrame URL: https://github.com/apache/spark/pull/23760#issuecomment-462607651 cc @BryanCutler, @viirya, @felixcheung, @icexelloss, @rxin, @gatorsmile, @shivaram, @falaki, @yanboliang Looks previous `collect` code wasn't performant enough. This optimization applies to `head` and `take` as well.
