This simple query creates a new dataset only including those rows where the ‘age’ columns is greater than 18:
filter_rows(ds, {"query": "age: >18"} -> (dsf)

​
Inputs & Outputs

The following are the inputs expected by the step and the outputs it produces. These are generally columns (ds.first_name), datasets (ds or ds[["first_name", "last_name"]]) or models (referenced by name e.g. "churn-clf").
​
ds_in
dataset
required
An input dataset to filter.
​
ds_out
dataset
required
A dataset containing the same columns as the input dataset but without the filtered rows.

​
