Record Class SerializedEqualityValues

java.lang.Object
java.lang.Record
org.apache.iceberg.flink.maintenance.operator.SerializedEqualityValues
@Internal public record SerializedEqualityValues(byte[] data) extends Record
Serialized primary key used as a Flink keyed state key. Wraps the raw bytes with content-based equals/hashCode so that Flink's keyBy partitions by key value, not by reference.

Using the full serialized key (instead of a hash) eliminates hash collisions: two distinct primary keys always map to separate Flink state entries.

      public SerializedEqualityValues(byte[] data)
      Creates an instance of a SerializedEqualityValues record class.
      Parameters:
      data - the value for the data record component

  • Method Details

    • equals

      public boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • hashCode

      public int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • data

      public byte[] data()
      Returns the value of the data record component.
      Returns:
      the value of the data record component
