Re: [VOTE] KIP-1340: Expose Both Mapped Key and Stream Key in Streams-GlobalKTable Joins
Posted by Lucy Liu via dev <de...@kafka.apache.org>.
Hi all,
I have a small update regarding the KIP:
For the new valueJoiner functional interface, I renamed it and reordered
the params:
Old: ValueJoinerWithMappedAndStreamKey<TableKey, StreamKey, StreamValue,
TableValue, VOut>
New: ValueJoinerWithStreamAndMappedKey<StreamKey, TableKey, StreamValue,
TableValue, VOut>
This change is to make the parameter order like `Key1, Key2, Value1,
Value2`, which is more natural than `Key2, Key1, Value1, Value2` in terms
of semantics.
Let me know if you have any questions or concerns regarding this change.
Thanks!
Best,
Lucy Liu

Hi all,
Sorry for the confusion earlier. The KIP has now received three binding +1
votes and 1 non-binding +1 vote, and has been accepted.
- Binding +1: Bill, Matthias, Frank

Thanks all for the review!

Lucy, a vote must stay open for at least 72h. No need to follow up, in
case nobody else replies, but technically we need to accept votes at
least until the 72h passed.
