Package org.apache.druid.segment.serde

Class NestedCommonFormatColumnPartSerde

java.lang.Object

org.apache.druid.segment.serde.NestedCommonFormatColumnPartSerde

All Implemented Interfaces:

ColumnPartSerde

public class NestedCommonFormatColumnPartSerde
extends Object
implements ColumnPartSerde

ColumnPartSerde shared by all NestedCommonFormatColumn. The logicalType defines the native Druid type of the column to use for things like ColumnCapabilities and hasNulls if any null values are present. If isVariantType is set, the column internally is composed of a mix of types, this is currently only used by VariantColumnAndIndexSupplier.

• ScalarLongColumnAndIndexSupplier
