Package io.trino.parquet.reader.decoders

Class RleBitPackingHybridDecoder

java.lang.Object

io.trino.parquet.reader.decoders.RleBitPackingHybridDecoder

All Implemented Interfaces:

ValueDecoder<int[]>

public final class RleBitPackingHybridDecoder
extends Object
implements ValueDecoder<int[]>

Run Length Encoding / Bit-Packing Hybrid (RLE) This class is similar to NullsDecoder but specialized for reading integers stored in bit width of 0 - 32. It is used specifically for decoding dictionary ids currently. It can be used for decoding definition and repetition levels of nested columns in future.
