Hi everyone! What happens if I have 2 alpakka-kafka Committer.sinkWithOffsetContexts which try to commit the same message offset? In our setup - due to the complexity of the stream-graph - it could happen that a single offset could be committed multiple times (e.g. when messages get multiplied with mapConcat and routed to different sinks).. Will there be any hickups or errors if the same

This field indicates how many acknowledgements the leader broker must receive from ISR (in-sync-replicas) brokers before responding to the request: 0=broker does not send any response, 1=broker will wait until the data is written to local log before sending a response, -1=broker will block until message is committed by all in sync replicas (ISRs) or broker's in.sync.replicas setting before

It is meant to give a readable guide to the protocol that covers the available requests, their binary format, and the proper way to make use of them to implement a client. The text was updated successfully, but these errors were encountered: I noticed that my Spring Kafka consumer suddenly fails when the group coordinator is lost. I'm not really sure why and i dont think increasing the max.poll.interval.ms will do anything since the time is set to 300 seconds. using:

kafka 2.01 重启kafka错误就会消失. 你期待的结果是什么？实际看到的错误信息又是什么？ 报错如下： camel.component.kafka.fetch-max-bytes. The maximum amount of data the server should return for a fetch request This is not an absolute maximum, if the first message in the first non-empty partition of the fetch is larger than this value, the message will still be returned to ensure that the consumer can make progress. fetch 请求和返回都是有固定格式的（不然也不认识），这就是kafka 内部的fetch 协议，不同的格式，就是不同的版本，以 fetch request (有请求协议，就有响应协议 )v0 和v1 举例 2018-09-14 · This should be similar to scenario 4 with full isolation of the leader. They have many similarities.

Maximum Kafka protocol request message size. Due to differing framing overhead between protocol versions the producer is unable to reliably enforce a strict max message limit at produce time and may exceed the maximum size by one message in protocol ProduceRequests, the broker will enforce the the topic's max.message.bytes limit (see Apache Kafka documentation). But, the same code is working fine with Kafka 0.8.2.1 cluster.

Hi, running Flink 1.10.0 we see these logs once in a while 2020-10-21 15: 48:57,625 INFO That's fine I can look at upgrading the client and/or Kafka. But I'm trying to understand what happens in terms of the source and the sink. It looks let we get duplicates on the sink and I'm guessing it's because the consumer is failing and at that point Flink stays on that checkpoint until it can reconnect and process that offset and hence the duplicates downstream? Hi John, The log message you saw from Kafka consumer simply means the consumer was disconnected from the broker that FetchRequest was supposed to be sent to. The disconnection can happen in many cases, such as broker down, network glitches, etc. max.partition.fetch.bytes: the maximum number of bytes returned by one partition on the broker upon a single pull.

It is meant to give a readable guide to the protocol that covers the available requests, their binary format, and the proper way to make use of them to implement a client. using kafka input plugin, I set client_id=d9f37fcb and consumer_threads => 3 [org.apache.kafka.clients.FetchSessionHandler] [Consumer clientId=d9f37fcb-0, groupId=default_logstash1535012319052] There's no exception or error when it happens, but the Kafka logs will show that the consumers are stuck trying to rejoin the group and assign partitions. There are a few possible causes: Make sure that your request.timeout.ms is at least the recommended value of 60000 and your session.timeout.ms is at least the recommended value of 30000.
