Yadong Qi updated CARBONDATA-781:
---------------------------------
Description: When I load carbondata 1000+ times with 35 nodes, I found SegmentProperties objects occupy 2.5+G(76K * 35 * 1000) memory in driver. I don't have small files so I don't want to compact the segments. I analyzed the dump file and found the values of SegmentProperties are the same, so I think we can reuse the SegmentProperties object if possible.
