Hi All, Currently in carbondata after a table is created once it becomes immutable. Deletion or addition of column is not supported because of which the same table and data cannot be used again. To add more flexibility to the carbondata system alter table support needs to be added to carbondata system.
Please refer the design document at below location and share your suggestions. https://drive.google.com/file/d/0B1DnrpMgGOu9dGxYMzVJUXEyZG8/view?usp=sharing Regards Manish Gupta
