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.

Note

As all collection members are required to be lazy frames, the returned collection’s members are still “lazy”. However, they are “shallow-lazy”, meaning they are obtained by calling .collect().lazy().
