[jira] [Created] (CARBONDATA-2685) make datamap rebuild for all
segments in parallel
xuchuanyin created CARBONDATA-2685:
--------------------------------------
Summary: make datamap rebuild for all segments in parallel
Key: CARBONDATA-2685
URL: https://issues.apache.org/jira/browse/CARBONDATA-2685
Project: CarbonData
Issue Type: Sub-task
Reporter: xuchuanyin
Assignee: xuchuanyin
Currently in carbondata, while rebuilding datamap, one spark job will be
started for each segment and all the jobs are executed serially. If we
have many historical segments, the rebuild will take a lot of time.
