Hi @jihoonson
I have updated the patch as following:
- Added PURGE option.
- When adding partition to a table, the partition's location will be made
by force.
- When dropping partition for a managed table, the location and meta data
will be removed.
- When dropping partition for an external table, the location will not be
remove. Only meta data will be remove. If users want to remove the location,
users need to specify PURGE option.
- Added a document for alter table statement.
Could you review the patch again?
