Walker Carlson created KAFKA-9298:
-------------------------------------
Summary: Reuse of a mapped stream causes an Invalid Topology
Key: KAFKA-9298
URL: https://issues.apache.org/jira/browse/KAFKA-9298
Project: Kafka
Issue Type: Bug
Components: streams
Reporter: Walker Carlson
Can be found with in the KStreamKStreamJoinTest.java
@Test
public void optimizerIsEager() {
final StreamsBuilder builder = new StreamsBuilder();
final KStream<String, String> stream1 = builder.stream("topic",
Consumed.with(Serdes.String(), Serdes.String()));
final KStream<String, String> stream2 = builder.stream("topic2",
Consumed.with(Serdes.String(), Serdes.String()));
final KStream<String, String> stream3 = builder.stream("topic3",
Consumed.with(Serdes.String(), Serdes.String()));
final KStream<String, String> newStream = stream1.map((k, v) -> new
KeyValue<>(v, k));
newStream.join(stream2,
(value1, value2) -> value1 + value2,
JoinWindows.of(ofMillis(100)),
StreamJoined.with(Serdes.String(), Serdes.String(),
Serdes.String()));
newStream.join(stream3,
(value1, value2) -> value1 + value2,
JoinWindows.of(ofMillis(100)),
StreamJoined.with(Serdes.String(), Serdes.String(),
Serdes.String()));
System.err.println(builder.build().describe().toString());
}
results in
Invalid topology: Topic KSTREAM-MAP-0000000003-repartition has already been
registered by another source.
org.apache.kafka.streams.errors.TopologyException: Invalid topology: Topic
KSTREAM-MAP-0000000003-repartition has already been registered by another
