Package org.apache.pinot.segment.local.segment.index.readers.forward

Class FixedBitMVEntryDictForwardIndexReader

java.lang.Object

org.apache.pinot.segment.local.segment.index.readers.forward.FixedBitMVEntryDictForwardIndexReader

All Implemented Interfaces:

Closeable, AutoCloseable, IndexReader, ForwardIndexReader<ForwardIndexReaderContext>

public final class FixedBitMVEntryDictForwardIndexReader
extends Object
implements ForwardIndexReader<ForwardIndexReaderContext>

Bit-compressed dictionary-encoded forward index reader for multi-value columns, where a second level dictionary encoding for multi-value entries (instead of individual values within the entry) are maintained within the forward index. See FixedBitMVEntryDictForwardIndexWriter for index layout.
