Collection.collect_all

Collection.collect_all() → Self

Collect all members of the collection.

This method collects all members in parallel for maximum efficiency. It is particularly useful when filter() is called with lazy frame inputs.

Returns:

The same collection with all members collected once. Members annotated with DataFrame are returned as DataFrames, while members annotated with LazyFrame are returned as “shallow-lazy” frames (obtained by calling .collect().lazy()).
