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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
