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

invalid reference

#getEffectiveSpec(IndexSpec)

, which will fill in any values which were not specified from IndexSpec.getAutoColumnFormatSpec(), falling back to hard-coded defaults, useful when generating segments or comparing compaction state.

 BitmapSerdeFactory bitmapEncoding)

Internal constructor used by NestedCommonFormatColumnFormatSpec.Builder to set bitmapEncoding during the process of resolving values for getEffectiveFormatSpec(NestedCommonFormatColumnFormatSpec, IndexSpec). bitmapEncoding cannot vary per column, and is always set from IndexSpec.getBitmapSerdeFactory().

getEffectiveFormatSpec

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

Create a NestedCommonFormatColumnFormatSpec with all fields fully populated. Values from the supplied column format spec take priority, any null values are then populated by checking IndexSpec.getAutoColumnFormatSpec(), then falling back to fields on IndexSpec itself if applicable, and finally resorting to hard coded defaults.
