Subject [jira] [Commented] (HIVE-446) Implement TRUNCATE
Date Fri, 12 Apr 2013 16:24:18 GMT


Gang Tim Liu commented on HIVE-446:

"External table" is used in the context where data is not fully managed. If it ends up that
there is a need to remove data behind external table, a question can be asked "why do you
define it as external table?".

Saying that, possibly the proposed syntax and semantics are not consistent to "external table"
use case.
