Class EnrichedRowData

java.lang.Object

org.apache.flink.connector.file.table.EnrichedRowData

All Implemented Interfaces:

org.apache.flink.table.data.RowData

@Internal
public class EnrichedRowData
extends Object
implements org.apache.flink.table.data.RowData

An implementation of RowData which is backed by two RowData with a well-defined index mapping, One of the rows is fixed, while the other can be swapped for performant changes in hot code paths. The RowKind is inherited from the mutable row.

EnrichedRowData

public EnrichedRowData(org.apache.flink.table.data.RowData fixedRow,
                       int[] indexMapping)

Method Detail

replaceMutableRow

public EnrichedRowData replaceMutableRow(org.apache.flink.table.data.RowData mutableRow)

Replaces the mutable RowData backing this EnrichedRowData.

This method replaces the mutable row data in place and does not return a new object. This is done for performance reasons.

from

public static EnrichedRowData from(org.apache.flink.table.data.RowData fixedRow,
                                   List<String> producedRowFields,
                                   List<String> mutableRowFields,
                                   List<String> fixedRowFields)

Creates a new EnrichedRowData with the provided fixedRow as the immutable static row, and uses the producedRowFields, fixedRowFields and mutableRowFields arguments to compute the indexes mapping.

The producedRowFields should include the name of fields of the full row once mutable and fixed rows are merged, while fixedRowFields and mutableRowFields should contain respectively the field names of fixed row and mutable row. All the lists are ordered with indexes matching the position of the field in the row. As an example, for a complete row (a, b, c) the mutable row might be (a, c) and the fixed row might be (b)

computeIndexMapping

public static int[] computeIndexMapping(List<String> producedRowFields,
                                        List<String> mutableRowFields,
                                        List<String> fixedRowFields)

This method computes the index mapping for EnrichedRowData.
