Head commit for run: 643b0a2676855046022f92aa77284d6d08b389ba / Arvid Heise <[email protected]> [FLINK-39792] Add multi-headers metadata key to Kafka connector The existing headers metadata key (MAP<STRING, BYTES>) silently drops duplicate header keys and loses insertion order, since iteration into a HashMap lets the last value win. The new multi-headers key exposes headers as ARRAY<ROW<name STRING, value BYTES>>, preserving wire order and duplicate keys faithfully on both source and sink sides. The two keys are mutually exclusive on the write path: declaring both in the same table schema is rejected at planning time with a ValidationException. Null header values are preserved; null header keys throw IllegalArgumentException since the Kafka protocol does not permit them.
