Hi his is with my streaming app kafka 10.1.0.
My flow looks something like below source topic stream -> filter for null value ->map to make it keyed by id ->custom processor to mystore -> to another topic -> ktable I am hitting the below type of exception in a custom processor class if I try to access offset() or partition() or timestamp() from the ProcessorContext in the process() method. I was hoping it would return the partition and offset for the enclosing topic(in this case source topic) where its consuming from or -1 based on the api docs. Looks like only in certain cases it is accessible. is it getting lost in transformation phases. Same issue happens on if i try to access them in punctuate() method but some where I saw that it might not work in punctuate(). Any reason for this or any link describing this will be helpful ==================================================================== java.lang.IllegalStateException: This should not happen as offset() should only be called while a record is processed at org.apache.kafka.streams.processor.internals.ProcessorContextImpl.offset(ProcessorContextImpl.java:181) ~[kafka-streams-0.10.1.0.jar!/:?] at com.sai.repo.MyStore.process(MyStore.java:72) ~[classes!/:?] at com.sai.repo.MyStore.process(MyStore.java:39) ~[classes!/:?] at org.apache.kafka.streams.processor.internals.ProcessorNode.process(ProcessorNode.java:82) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.ProcessorContextImpl.forward(ProcessorContextImpl.java:204) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.kstream.internals.KStreamMap$KStreamMapProcessor.process(KStreamMap.java:43) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.ProcessorNode.process(ProcessorNode.java:82) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.ProcessorContextImpl.forward(ProcessorContextImpl.java:204) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.kstream.internals.KStreamFilter$KStreamFilterProcessor.process(KStreamFilter.java:44) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.ProcessorNode.process(ProcessorNode.java:82) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.ProcessorContextImpl.forward(ProcessorContextImpl.java:204) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.SourceNode.process(SourceNode.java:66) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.StreamTask.process(StreamTask.java:181) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.StreamThread.runLoop(StreamThread.java:436) ~[kafka-streams-0.10.1.0.jar!/:?] at org.apache.kafka.streams.processor.internals.StreamThread.run(StreamThread.java:242) [kafka-streams-0.10.1.0.jar!/:?] ===================================================================== Regards Sai
