Each field of this corresponds to a field in the manifest file's partition spec.

Member Data Documentation

contains_nan

std::optional<bool> iceberg::PartitionFieldSummary::contains_nan

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

contains_null

bool iceberg::PartitionFieldSummary::contains_null = true

Field id: 509 Whether the manifest contains at least one partition with a null value for the field

kContainsNaN

const SchemaField iceberg::PartitionFieldSummary::kContainsNaN

inlinestatic

Initial value:

=
      SchemaField::MakeOptional(518, "contains_nan", iceberg::boolean(),
                                "True if any file has a nan partition value")

kContainsNull

const SchemaField iceberg::PartitionFieldSummary::kContainsNull

inlinestatic

Initial value:

=
      SchemaField::MakeRequired(509, "contains_null", iceberg::boolean(),

kLowerBound

const SchemaField iceberg::PartitionFieldSummary::kLowerBound

inlinestatic

Initial value:

= SchemaField::MakeOptional(
      510, "lower_bound", iceberg::binary(), "Partition lower bound for all files")

kUpperBound

      511, "upper_bound", iceberg::binary(), "Partition upper bound for all files")

lower_bound

std::optional<std::vector<uint8_t> > iceberg::PartitionFieldSummary::lower_bound

Field id: 510 Lower bound for the non-null, non-NaN values in the partition field, or null if all values are null or NaN

upper_bound

std::optional<std::vector<uint8_t> > iceberg::PartitionFieldSummary::upper_bound
