data_save()

Save a DataFrame and record its hash.

Usage

data_save(
    data: pd.DataFrame,
    path: str,
    type: str | None = None,
    delimiter: str = 'comma',
    locked: bool = True,
    force: bool = False,
) -> pd.DataFrame

Arguments

Name	Type	Default	Description
data required	pd.DataFrame		The data to save.
path required	str		A catalog name such as `"inputs.intermediate.cleaned"` or a file path ending in `.csv` or `.parquet`. A name's leading parts select a folder from `directories`: the longest run that names a key, such as `inputs_intermediate` or `inputs_private_raw`. The rest becomes the file name. A name is also added to the data catalog, so `data_read()` finds it.
type	str \| None	None	`"parquet"` or `"csv"`. Default: from the file extension, or Parquet for a catalog name.
delimiter	str	'comma'	Delimiter for CSV files: comma, tab, semicolon, or space.
locked	bool	True	Whether later reads must find the file unchanged.
force	bool	False	Create the folder if it does not exist.

Value

data, so the call can end a pipeline.
