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.
Available 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).
