> When I load carbondata 1000+ times with 35 nodes, I found SegmentProperties occupy 2.5+G(76K * 35 * 1000) memory in driver. I don't have small files so I don't want to compate the segment. I analyze the dump file and found the value of SegmentProperties are the same, so I think we can reuse the SegmentProperties if possible.
