I will merge this PR this week if nobody object. Different from the [previous one](https://github.com/apache/spark/pull/27360), this PR will not cause performace regression on sparse datasets by default (since default `blockSize`=1, and the original impl is used). For expert users, they can tune `blockSize` for better performance. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
