-Re: [jira] [Created] (HIVE-4844) Add char/varchar data types

As for the param types. How do we enforce these? If we have a lazy simple
serde and a varchar 10 and we are reading a column with 11 chars, what do
Maybe we say that char is an alias and we do not actually enforce anything.

some initial questions. I understand that your patch is still in progress,
but I'm wondering what's your thought on how you plan to store the type
params. Obviously, type params are metadata of a column, which needs to be
stored. I assume that hive schema needs to change to accommodate this.
