Class DefaultIndexReaderProvider

java.lang.Object

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

All Implemented Interfaces:

BloomFilterReaderProvider, ForwardIndexReaderProvider, GeospatialIndexReaderProvider, IndexReaderProvider, InvertedIndexReaderProvider, JsonIndexReaderProvider, RangeIndexReaderProvider, SortedIndexReaderProvider, TextIndexReaderProvider

public class DefaultIndexReaderProvider
extends Object
implements IndexReaderProvider

Default implementations of index reader provision logic. This class should not be instantiated but accessed via {@see IndexReaderProviders#getIndexReaderProvider} so this logic may be overridden by users of the SPI. Unless an override is specified, this is the logic which will be used to construct readers for data buffers.
