Derived properties for the universal ArrayND.

The ArrayNDProperties has a one-to-one mapping to a protobuf ArrayNDProperties.

Fields

num_records: Option<i64>

Defined if the number of records is known statically (set by the resize component)

num_columns: Option<i64>

nullity: bool

true if the data may contain null values

releasable: bool

set to true by the mechanisms. Acts as a filter on the values in the release

c_stability: u32

amplification of privacy usage by unstable data transformations, or possibility of duplicated records

aggregator: Option<AggregatorProperties>

set when data is aggregated, used to help compute sensitivity from the mechanisms

nature: Option<Nature>

either min/max or categories

data_type: DataType

f64, i64, bool, String

dataset_id: Option<i64>

index of last Materialize or Filter node, where dataset was created used to determine if arrays are conformable even when N is not known

node_id: i64

node index of the value

is_not_empty: bool

true if the number of rows is known to not be length zero

dimensionality: Option<i64>

number of axes in the array

group_id: Vec<GroupId>

used for tracking subpartitions

naturally_ordered: bool

used to determine if order of rows has changed

sample_proportion: Option<f64>

proportion of original data sampled
