InvalidStateStoreException on KStream join using GlobalKtables

Question

I have a Kafka Streams application where I am joining a KStream that reads from "topic1" with a GlobalKTable that reads from "topic2" and then with another GlobalKTable that reads from "topic3".

When I try to push messages to all 3 topics at the same time then I get following exception -

org.apache.kafka.streams.errors.InvalidStateStoreException

If I push messages one by one in these topics i.e push messages in topic2 then in topic3 and then in topic1, then I do not get this exception.

I have also added StateListener before I start KafkaStreams

KafkaStreams.StateListener stateListener = new KafkaStreams.StateListener() {
            @Override
            public void onChange (KafkaStreams.State newState, KafkaStreams.State oldState) {
                if(newState == KafkaStreams.State.REBALANCING) {
                    try {
                        Thread.sleep(1000);
                    }
                    catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        };
streams.setStateListener(stateListener);
streams.start();

Also I wait till the store is queryable after the stream has started by calling following method

public static  <T> T waitUntilStoreIsQueryable(final String storeName,
                                                   final QueryableStoreType<T> queryableStoreType,
                                                   final KafkaStreams streams) throws InterruptedException {
        while (true) {
            try {
                return streams.store(storeName, queryableStoreType);
            } catch (final InvalidStateStoreException ignored) {
                // store not yet ready for querying
                Thread.sleep(100);
            }
        }
    }

Following is the Kafka Streams and GlobalKTable join code:

KStream<String, GenericRecord> topic1KStream =
           builder.stream(
               "topic1",
               Consumed.with(Serdes.String(), genericRecordSerde)
           );
GlobalKTable<String, GenericRecord> topic2KTable =
           builder.globalTable(
               "topic2",
               Consumed.with(Serdes.String(), genericRecordSerde),
               Materialized.<String, GenericRecord, KeyValueStore<Bytes, byte[]>>as("topic2-global-store")
                   .withKeySerde(Serdes.String())
                   .withValueSerde(genericRecordSerde)
           );
  GlobalKTable<String, GenericRecord> topic3KTable =
           builder.globalTable(
               "topic3",
               Consumed.with(Serdes.String(), genericRecordSerde),
               Materialized.<String, GenericRecord, KeyValueStore<Bytes, byte[]>>as("topic3-global-store")
                   .withKeySerde(Serdes.String())
                   .withValueSerde(genericRecordSerde)
           );

KStream<String, MergedObj> stream_topic1_topic2 = topic1KStream.join(
           topic2KTable,
           (topic2Id, topic1Obj) -> topic1.get("id").toString(),
           (topic1Obj, topic2Obj) -> new MergedObj(topic1Obj, topic2Obj)
       );
       final KStream<String, GenericRecord> enrichedStream =
        stream_topic1_topic2.join(
           topic3KTable,
           (topic2Id, mergedObj) -> mergedObj.topic3Id(),
           (mergedObj, topic3Obj) -> new Enriched(
               mergedObj.topic1Obj,
               mergedObj.topic2Obj,
               topic3Obj
           ).enrich()
       );
enrichedStream.to("enrichedStreamTopic", Produced.with(Serdes.String(),getGenericRecordSerde()));

The above code is very similar to this.

When I try to push messages to all 3 topics at the same time then I get following exception:

org.apache.kafka.streams.errors.StreamsException: Exception caught in process. taskId=0_1, processor=KSTREAM-SOURCE-0000000000, topic=topic1,
partition=1, offset=61465,

I fixed the issue in my code I had auto.register.schemas=false because I had manually registered schemas for all my topics.

After I set auto.register.schemas=true and re-ran streams application it worked fine. I think it needs this flag for its internal topics.
