[jira] [Created] (KAFKA-8697) Kafka consumer group auto removal
Pavel Rogovoy created KAFKA-8697: Summary: Kafka consumer group auto removal Key: KAFKA-8697 URL: https://issues.apache.org/jira/browse/KAFKA-8697 Project: Kafka Issue Type: Improvement Reporter: Pavel Rogovoy Hello everyone, I'm new to Kafka so please be gentle with me :) Current issue: Lets say I have a consumer that consumes messages from a consumer group named 'ABC' and decides to terminate. Consumer group 'ABC' will now stay there hanging with zero consumers. This situation will cause monitoring tools like burrow to alert on a lag for this consumer group even though my application has finished its job and doesn't want to do anything and thus not in lag. I think it will be useful if we will add an option to create a consumer group that will be automatically removed when the last consumer has terminated properly and did not crashed.

[jira] [Commented] (KAFKA-8675) "Main" consumers are not unsubsribed on KafkaStreams.close()

Sax commented on KAFKA-8675: Calling `Consumer#close()` should be sufficient. It's should not be required to call `unsubscribe()`. The log message you see, is due to the fact that KafkaStreams used the consumer slightly differently, and that the consumer does not send a "leave group request" on close. This is by-design. I think we can close this ticket a "not a problem". > "Main" consumers are not unsubsribed on KafkaStreams.close() > > > Key: KAFKA-8675 > URL: https://issues.apache.org/jira/browse/KAFKA-8675 > Project: Kafka > Issue Type: Bug > Components: streams >Affects Versions: 2.2.1 >Reporter: Modestas Vainius >Priority: Major > > Hi! > It seems that {{KafkaStreams.close()}} never unsubscribes "main" kafka > consumers.

[jira] [Commented] (KAFKA-8673) Kafka stream threads stuck while sending offsets to transaction preventing join group from completing

Threads who are parked on KafkaProducer.sendOffsetsToTransaction should not park forever: although TxnRequestHandler would retry infinitely when getting request timeout / node disconnects, once the broker is back up online they requests should be responded and then TransactionalRequestResult.await could return. From the source code I cannot find anywhere why this is not happening --- maybe it needs some time to clean all the re-enqueued requests, but it should not block forever, could you confirm that even until brokers are all up and running and handling requests normally, these threads are still blocked on the call for very long time? 2. Other threads waiting on join-group requests for these blocked threads: this should actually now be resolved as part of https://issues.apache.org/jira/browse/KAFKA-6399, which is in 2.3.0. In other words when some threads are blocked, they would still be kicked out of the group upon rebalance timeout which is now not infinity anymore. > Kafka stream threads stuck while sending offsets to transaction preventing > join group from completing > - > > Key: KAFKA-8673 > URL: https://issues.apache.org/jira/browse/KAFKA-8673 > Project: Kafka > Issue Type: Bug > Components: consumer, streams >Affects Versions: 2.2.0 >Reporter: Varsha Abhinandan >Priority: Major > Attachments: Screen Shot 2019-07-11 at 12.08.09 PM.png > > > We observed a deadlock kind of a situation in our Kafka streams application > when we accidentally shut down all the brokers.

[jira] [Updated] (KAFKA-8702) Kafka leader election doesn't happen when leader broker port is partitioned off the network

New connections fail to be created to one broker, or existing connections drop to it. The connection to Zookeeper however remains alive. When this happens to one broker, our remediation is to reboot the broker. The reboot causes offline partitions to start and they don't go away until the broker comes back online.

But it is not wrong to delete the record immediately since the broker-side log retention is independent of Streams processing logic: say if you process a record from topic A configured with 7 day retention, and writing the result to another topic B with 1 day retention only, then very likely you would see the results been deleted immediately as well. This is purely Kafka's log retention definition and should not be violated by Streams. > Under low traffic conditions purging repartition topics cause WARN statements > about UNKNOWN_PRODUCER_ID > - > > Key: KAFKA-7190 > URL: https://issues.apache.org/jira/browse/KAFKA-7190 > Project: Kafka > Issue Type: Improvement > Components: core, streams >Affects Versions: 1.1.0, 1.1.1 >Reporter: Bill Bejeck >Assignee: Guozhang Wang >Priority: Major > > When a streams application has little traffic, then it is possible that > consumer purging would delete > even the last message sent by a producer (i.e., all the messages sent by > this producer have been consumed and committed), and as a result, the broker > would delete that producer's ID.
