Accelerable

drop_col is always accelerable if the input is accelerable. A dataset that only uses accelerable verbs can be accelerated, making queries on the dataset respond faster.

Examples

drop_col debug_info, status_code

Exclude the columns ‘debug_info’ and ‘status_code’ from the data passed downstream.
