Class NestedCommonFormatColumnFormatSpec

java.lang.Object

org.apache.druid.segment.nested.NestedCommonFormatColumnFormatSpec

Direct Known Subclasses:

NestedCommonFormatColumnPartSerde.FormatSpec

public class NestedCommonFormatColumnFormatSpec
extends Object

Defines storage format for 'auto' and json columns. This can be convered into the 'effective' format spec by calling getEffectiveFormatSpec(NestedCommonFormatColumnFormatSpec, IndexSpec), useful when generating segments or comparing compaction state.

getEffectiveFormatSpec

public static NestedCommonFormatColumnFormatSpec getEffectiveFormatSpec(@Nullable
 NestedCommonFormatColumnFormatSpec columnFormatSpec,
 IndexSpec indexSpec)

Create a NestedCommonFormatColumnFormatSpec with all fields fully populated. Values are populated in the following order:

• value in the given column format spec, if non-null
• value in IndexSpec.getAutoColumnFormatSpec(), if non-null
• fall back to equivalent fields on IndexSpec itself if applicable
• hard coded defaults in DEFAULT
