KIP-1270 — Introduce ProcessExceptionalHandler for Global Thread
Accepted Kafka 4.3 Streams
Extends the ProcessingExceptionHandler to cover GlobalStreamThread processors (GlobalKTable), with a new processing.exception.handler.global.enabled boolean config to opt in. Currently any exception in GlobalKTable record processing kills the GlobalStreamThread and shuts down the entire Streams application, unlike regular KStream/KTable processing where the handler can recover gracefully.
