Hi In my POV the user should control the in-memory size of the datasets since the reason to separate the data set is to control the memory consumption of distributed data-consuming systems (like Spark, Presto, etc...). Moreover, the size of the final file of the data set depends on: number of columns * column type (int8/16/32, string, float... )* number of lines * compression. I can't see any benefit of controlling the number of the lines (besides the effect on the file size) -- This is an automated message from the Apache Git Service.
