Package org.apache.flink.connector.file.table

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.

  • Constructor Details

    • EnrichedRowData

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

  • Method Details

    • 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.

      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.
