Properties

ArrowDataset.PartitioningFactoryOptions:infer-dictionary

When inferring a schema for partition fields, yield dictionary encoded types instead of plain. This can be more efficient when materializing virtual columns, and Expressions parsed by the finished Partitioning will include dictionaries of all unique inspected values for each field.

since: 11.0.0

ArrowDataset.PartitioningFactoryOptions:schema

Optionally, an expected schema can be provided, in which case inference will only check discovered fields against the schema and update internal state (such as dictionaries).

since: 11.0.0

ArrowDataset.PartitioningFactoryOptions:segment-encoding

After splitting a path into components, decode the path components before parsing according to this scheme.
