Methods in org.apache.druid.segment that return DimensionMergerV9

Modifier and Type	Method	Description
default DimensionMergerV9	DimensionHandler.makeMerger(String outputName, IndexSpec indexSpec, SegmentWriteOutMedium segmentWriteOutMedium, ColumnCapabilities capabilities, ProgressIndicator progress, File segmentBaseDir, Closer closer)	Creates a new DimensionMergerV9, a per-dimension object responsible for merging indexes/row data across segments and building the on-disk representation of a dimension.
default DimensionMergerV9	DimensionHandler.makeMerger(String outputName, IndexSpec indexSpec, SegmentWriteOutMedium segmentWriteOutMedium, ColumnCapabilities capabilities, ProgressIndicator progress, Closer closer)	Deprecated. use DimensionHandler.makeMerger(String, IndexSpec, SegmentWriteOutMedium, ColumnCapabilities, ProgressIndicator, File, Closer) This method exists for backwards compatiblity with older versions of Druid since this is an unofficial extension point that must be implemented to create custom dimension types, and will be removed in a future release.

void	AutoTypeColumnMerger.attachParent(DimensionMergerV9 parent, List<IndexableAdapter> projectionAdapters)
default void	DimensionMergerV9.attachParent(DimensionMergerV9 parent, List<IndexableAdapter> projectionAdapters)	Attaches the DimensionMergerV9 of a "projection" parent column so that stuff like value dictionaries can be shared between parent and child.
