Hi,
We recently saw a split-brain behavior happened in production.
There were a controller switch, and then unclean leader elections.
It led to 24 partitions (out of 70) had 2 leaders for 2 days until I
restarted the broker. Producers and consumers were talking to different
"leaders" so the recor
Hi All,
Could you please help me in getting count of all messages stored in kafka
from a particular offset?
I have tried GetOffsetShell command, it is not giving me.
Kind Regards,

Hi John and Matthias
thanks for the questions, maybe explaining our use case helps a bit:
We are receiving CDC records (row-level insert/update/delete) in one topic
per table. The key is derived from the DB records, the value is null in
case of deletes. Those would be the immutable facts I guess.

Hi all!
I was trying to deploy a little Kafka cluster over Kubernetes (k8s), and
noticed this wonderful helm charts from here
https://github.com/confluentinc/cp-helm-charts
The Kafka chart included there, will try to expose the brokers so they can
be accesible not only from within the k8s cluster,

Hi
How long does your application run? More than the 60 seconds you set for commit
interval?
Have a look at
https://sematext.com/opensee/m/Kafka/uyzND1SdDRMgROjn?subj=Re+Kafka+Streams+why+aren+t+offsets+being+committed+
and check if your offsets are really comitted

Hey folks,
I am getting the below exception when using a mockSchemaRegsitry in a
junit test . I appreciate your help.I am using confluent 4.0
private SchemaRegistryClient schemaRegistry;
private KafkaAvroSerializer avroSerializer;
Properties defaultConfig = new Properties();

you can user kafkacat starting at that offset to head and pipe the output
to "wc -l" (word count).

Make sure to call `KafkaStreams#close()` to get the latest offsets
committed.
Beside this, you can check the consumer and Streams logs in DEBUG mode,
to see what offset is picked up (or not).

You set:
> senderProps.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,avroSerializer.getClass());
This will tell the Producer to create a new AvroSerailizer object, and
this object expects "schema.registry.url" to be set during
initialization, ie, you need to add the config to `senderProps`.

That is quite expensive to do...
Might be best to write a short Java program that uses
Consumer#endOffset() and Consumer#beginningOffsets()

Thanks Mathias . How do I deal with this scenario in the case of a
consumer that expects a specific record type ?.I am trying to write an
integration test for a scenario for the below scenairo.All of these uses
an avro object as the value for producer record .I am kind of able to
write this
You can use `ByteArrayDeserializer` to get `byte[]` key and value from
the consumer and deserialize both "manually" using AvorDeserializer that
is created with MockSchemaRegistry. `ConsumerRecord` also give you the
topic name for each record via #topic().
