[jira] [Created] (CARBONDATA-781) SegmentProperties occupy too much memory in driver

Yadong Qi created CARBONDATA-781:
------------------------------------

             Summary: SegmentProperties occupy too much memory in driver
                 Key: CARBONDATA-781
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-781
             Project: CarbonData
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.1.0-incubating
            Reporter: Yadong Qi
         Attachments: CarbonProperties.jpg

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.
