Package org.apache.iceberg.arrow.vectorized.parquet

Class VectorizedDictionaryEncodedParquetValuesReader

  • public class VectorizedDictionaryEncodedParquetValuesReader
extends BaseVectorizedParquetValuesReader
    This decoder reads Parquet dictionary encoded data in a vectorized fashion. Unlike other vectorized readers, methods in this decoder don't need to read definition levels. In other words, these methods are called when there are non-null values to be read.
