Hi all, I have found an old thread [1] where there was a question about SQL joins on nested fields.
The conclusion was that (quote): *"temporal table join doesn't support join on a nested join.In blink planner, a temporal table join will be translated into lookup joinwhich will use the equality condition fields as the lookup keys."* The thread is from 2020 and I was wondering if there is any plan/ticket about adding support for nested fields to lookup join/temporal join I've checked this use case on Flink 1.15.2 and it seems still not supported.
