Deleting data in Hustle is partition-oriented, which means you can’t remove specific rows as conventional database systems dose. There are two functions to do this with different granularities.
delete() function only deletes data but keeps the table definition. If a Table object specified, all data in that table will be deleted. To delete a particular range of partitions, pass it an Expr, for example, “impressions.date < ‘2014-01-01’”.

Use drop() function to delete the whole table, including data, all partitions, and table definition. Unlike delete(), it only takes a Table object to specify the table you want to drop.
