Yadong Qi updated CARBONDATA-781:
---------------------------------
Description: 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 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. (was: When I load carbondata 1000+
