Input/Output

Dataset

A dataset is a unit that consists of data payload and metadata.

Presently, whatif stores a dataset as a directory layout:

dataset_name/
|-- metadata.yaml
`-- data.csv

and loads the dataset into a a2rl.WiDataFrame.

In future, whatif may add additional implementations to support different storage layout.

list_sample_datasets	List the name of sample datasets included in whatif.
read_csv_dataset	Read a dataset directory into a a2rl.WiDataFrame.
sample_dataset_path	Resolve the path to the sample dataset.

Metadata

The metadata API is primarily intended for whatif developers.

Metadata	Metadata of a Whatif dataframe or dataset.
read_metadata	Load a YAML file into an in-memory metadata object.
save_metadata	Save an in-memory metadata object into a YAML file.
