org.apache.pinot.segment.local.segment.index.readers.OnHeapBytesDictionary

All Implemented Interfaces:

Closeable, AutoCloseable, Dictionary

public class OnHeapBytesDictionary
extends BaseImmutableDictionary

Implementation of BYTES dictionary that cache all values on-heap.

This is useful for BYTES columns that:

• Has low cardinality BYTES dictionary where memory footprint on-heap is acceptably small
• Is heavily queried
