ColumnSelectorFactory Factory class for MetricSelectors
CompressedVSizeIndexedSupplier Format - byte 1 - version offsets - indexed integers of length num of rows + 1 representing offsets of starting index of first element of each row in values index and last element equal to length of values column, the last element in the offsets represents the total length of values column.
CompressedVSizeIndexedV3Supplier The format is mostly the same with CompressedVSizeIndexedSupplier(which has version 0x2, so we call it V2), the only difference is V3's offsets is not VSize encoded, it's just compressed.

DimensionHandler Processing related interface A DimensionHandler is an object that encapsulates indexing, column merging/building, and querying operations for a given dimension type (e.g., dict-encoded String, Long).
DimensionIndexer Processing related interface A DimensionIndexer is a per-dimension stateful object that encapsulates type-specific operations and data structures used during the in-memory ingestion process (i.e., work done by IncrementalIndex).
DimensionMerger Processing related interface A DimensionMerger is a per-dimension stateful object that encapsulates type-specific operations and data structures used during the segment merging process (i.e., work done by IndexMerger/IndexMergerV9).
DimensionMergerLegacy Processing related interface DimensionMerger subclass to be used with the legacy IndexMerger.
DimensionMergerV9 Processing related interface DimensionMerger subclass to be used with IndexMergerV9.
