TableFileInput

class

class TableFileInput(file: Path, metadata: MetadataSpec | None = None)

Categories: spi

One parquet file SrcPlugin.read_in produces for an output slot, paired with optional metadata to carry alongside it.

Parameters

parameter

filePath

Path to the parquet file the plugin materialised under ctx.work_dir.

parameter

metadataMetadataSpec | None (dict[str, str | int | float | bool] | None)

Optional per-file MetadataSpec. Each entry is added as a metadata column on file's table, by convention named with a leading @. None (the common case) attaches nothing -- see to_table_file_inputs.
