Expand description

Field summary for partition field in the spec.

Each field in the list corresponds to a field in the manifest file’s partition spec.

Fields§

field: 518 Whether the manifest contains at least one partition with a NaN value for the field

§lower_bound: Option<Datum>

field: 510 The minimum value for the field in the manifests partitions.

§upper_bound: Option<Datum>

field: 511 The maximum value for the field in the manifests partitions.
