Constructor Detail

OrcBatchPageSource

public OrcBatchPageSource(OrcBatchRecordReader recordReader,
                          OrcDataSource orcDataSource,
                          List<HiveColumnHandle> columns,
                          TypeManager typeManager,
                          OrcAggregatedMemoryContext systemMemoryContext,
                          FileFormatDataSourceStats stats,
                          RuntimeStats runtimeStats,
                          List<Boolean> isRowNumberList,
                          byte[] rowIDPartitionComponent,
                          String rowGroupId)

Parameters:

columns - an ordered list of the fields to read

isRowNumberList - list of indices of columns. If true, then the column then the column at the same position in columns is a row number. If false, it isn't. This should have the same length as columns. #throws IllegalArgumentException if columns and isRowNumberList do not have the same size
