----------------------------------------
Summary: Support new optimized insert flow for Alter table
scenarios
Key: CARBONDATA-3720
URL: https://issues.apache.org/jira/browse/CARBONDATA-3720
Project: CarbonData
Issue Type: Sub-task
Reporter: Ajantha Bhat
Assignee: Ajantha Bhat
Fix For: 2.0.0
Currently, the rearrange logic is based on schema ordinal.
For alter table drop and add columns, schema ordinal based re arrange may not
work as index will be outside the projection size.
Hence don't use schema ordinal for rerrange, implemented a position map based
rearrange.
