Producer dies when producing to a just created topic · Issue #4904 · confluentinc/librdkafka · GitHub

Description

It can occasionally happen, that if we create a topic and immediately after we start producing to that topic the producer can fail with an "unknown topic or partition" message. That problem occurs regardless of topic.metadata.propagation.max.ms.

How to reproduce

When I'm running tests from the tests directory, a few of them fail with unknown topic or partition error, e.g.:

...
| 0042_many_topics                         |     FAILED | 903.862s | test_dr_msg_cb():1996: Message delivery (to rdkafkatest_rnd5c8f8ba61d9c48a0_0042_many_topics [0]) failed: expected Success, got Broker: Unknown topic or partition
...

Using our test application

start a test cluster
run

dotnet run -c Release --project /workspace/KafkaPlayground/dotnet/KafkaTool.csproj \
producer \
--config allow.auto.create.topics=false \
--config bootstrap.servers=$BROKERS \
--config debug=all \
--topics=3000 \
--partitions=1 \
--replication-factor=3 \
--min-isr=2 \
--topic-stem=my-topic \
--messages-per-second=50000 \
\
--config request.timeout.ms=195000 \
--config message.timeout.ms=195000 \
--config request.required.acks=-1 \
--config max.in.flight.requests.per.connection=1 \
--config topic.metadata.refresh.interval.ms=10000 \
--config topic.metadata.propagation.max.ms=75000 \
\
--reporting-cycle=1000 \
--recreate-topics-delay=10 \
--recreate-topics-batch-size=500 &> log.txt
