Class HoodieColumnRangeMetadata<T extends Comparable>

java.lang.Object

org.apache.hudi.common.model.HoodieColumnRangeMetadata<T>

All Implemented Interfaces:

Serializable

public class HoodieColumnRangeMetadata<T extends Comparable>
extends Object
implements Serializable

Hoodie metadata for the column range of data stored in columnar format (like Parquet) NOTE: Comparable is used as raw-type so that we can handle polymorphism, where caller apriori is not aware of the type HoodieColumnRangeMetadata is associated with
