> 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.
