Data Processing - Filtering Operations

Card Puncher Data Processing

About

filtering is a data processing operation that processes data through a filter where the data may be:

  • deleted according to a predicate from a collection
  • transformed (map operation)

Therefore, you need to be careful about what filter means. For instance:

Delete

A delete filter is expressed via a predicate. A predicate is developed as a function or operator that returns a boolean.
