Akshay created CARBONDATA-4179: ---------------------------------- Summary: Support rename/change datatype for complex columns Key: CARBONDATA-4179 URL: https://issues.apache.org/jira/browse/CARBONDATA-4179 Project: CarbonData Issue Type: Sub-task Reporter: Akshay
The following points will be considered for schema lets say- *str struct<a:int>* - 1) Rename parent name *str to str2* alter table test_rename change str str2 struct<a:int> 2) Rename child name from *a to b* alter table test_rename change str str struct<b:int> 3) Change datatype of *a* from *int to long* alter table test_rename change str str struct<a:long> *NOTE*- Renaming and changing datatype both operations should be done without changing the levels of the complex column. For example : 1) int cannot be converted to an array or struct. 2) array cannot be converted to struct and vice-versa -- This message was sent by Atlassian Jira (v8.3.4#803005)
