This PR tries to optimize the SegmentProcessorFramework that's used when to generate segments. Today, quicksort is conducted over the data file that's memory mapped. If the data file is huge, random reads lead to page faults that slow down sorting. This PR tries an idea to extract the sort fields into a temp file for better data locality for sorting, mainly for use cases where the input files are full of very wide rows but just sort on a single column. -- This is an automated message from the Apache Git Service.
