This KIP won't change any public interfaces. However, It it will change the behavior of the following:

Operators

  • left join Kstream-Kstream: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
  • outer join Kstream-Kstream: no longer drop left/right records with null-key and call ValueJoiner with 'null' for right/left value.
  • left-foreign-key join Ktable-Ktable: no longer drop left records with null-foreign-key returned by the ForeignKeyExtractor and call ValueJoiner with 'null' for right value.
  • left join KStream-Ktable: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
  • left join KStream-GlobalTable: no longer drop left records with null-key and call KeyValueMapper with 'null' for left  key. The case where KeyValueMapper returns null is already handled in the current implementation.
