Class VectorizedDictionaryEncodedParquetValuesReader

java.lang.Object

org.apache.parquet.column.values.ValuesReader

org.apache.iceberg.arrow.vectorized.parquet.BaseVectorizedParquetValuesReader

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