-----------------------------------------------
bq.if we set table disable_delete, could user see this table?
I think here the user should be able to see until the table is really deleted.
bq.create the table with the same name, is it will something wrong?
If drop is done completely then we should allow the table creation with same
name. Maybe till then we should not allow. Just my thoughts on this.
> Support an option to keep data of dropped table for some time

> User may drop table accidentally because of error code or other uncertain
> reasons.
> Unfortunately, it happens in our environment because one user make a mistake
> between production cluster and testing cluster.
> So, I just give a suggestion, do we need to support an option to keep data of
> dropped table for some time, e.g. 1 day
> In the patch:
> We make a new dir named .trashtables in the rood dir.
> In the DeleteTableHandler, we move files in dropped table's dir to trash
> table dir instead of deleting them directly.
> And Create new class TrashCleaner which will clean dropped tables if it is
> time out with a period check.
> Default keep time for dropped tables is 1 day, and check period is 1 hour.
