Data Operation - Truncate

About

truncate is a intermediate operation that will delete the content of a data resource but not it's metadata

Truncate supports the following arguments:

Name	Default	Description
force	false	Delete the foreign keys constraints if true
cascade	false	Truncate recursively the dependent resources
processing-type	batch	The processing type (all at once or one by one)

If you want to truncate in a stream fashion (ie one by one), you should set the order argument of the select to drop so that the tables are truncated in order.
force is applied in batch mode only if all foreign tables are present in the batch.
the truncated data resources are returned
on a file system, force or cascade have the same effect, they will truncate all files recursively in a directory.

Truncate is also available via the data truncate command
