Thanks for the input.
I do plan on reducing the heap for the next restart. Initially I'd thought
that less heap memory could also be the reason but since then I've learned
that cannot be the issue.
I also found the number 262144 online but I believe those results were
related to Elastic Search.

If you only enable "read_committed", yes.
If you set `processing.guarantees="exactly_once"` the guarantee is
stronger, because using a read-process-write pattern allows to couple
writing result data and committing offsets into a single transaction (in
contrast to a consumer-only scenario, for whic
This is not only a configuration. Like in all messaging solutions you need to
make sure that all involved applications ensure once and only once delivery
from producer(s) over Kafka to consumer(s).

Hello again,
after like 15 minutes I have now this result:

Hello,
I just ran the kafka-reassign-partitions with --generate to create the
json and then with --execute to run it.
Now when checking with --verify I can see that the 4 partitions (it now
changed from only one partitions not having all in ISR to 12 not being
all in ISR) are successful, but t
Does a Kafka Streams consumer also have that same limitation of possible
duplicates?
Thanks,
Chris

1.0.1 is very old version of Kafka. Is there any chance you would consider
a rolling upgrade ?

Have you got any producers using an older version of Kafka? Does the broker
with high CPU usage contain the leader of any topics which don't have leaders
on other brokers? Is the server.properties file the same across all brokers
(minus broker.id etc)?
Many Thanks,
Jamie

Hi,
I missed the original email, but I know Sematext can monitor your
containerized/k8sized Kafka.
Maybe of interest: https://sematext.com/blog/monitoring-kafka-with-sematext/

Hi,
We are implementing a use case that needs tight at least once delivery.
Even in the case of failures of nodes, no messages must be lost.
We are trying to find out the least restrictive configurations that can
give us at least once delivery. Following is what we found.

If we use ack
I'm using the Prometheus jmx_exporter to export key metrics from the
brokers. Takes a bit of fiddling to get the regexes right, but works well.

Hey thanks for your response.
I was thinking along the same lines. Cruise Control comes with good set of
monitoring functions, but not ready for K8s. You would need to deploy that
as a container (no official image yet). Do you know if any k8s flavour has
been made available yet ?
Prometheus/graf

Hi,
personally speaking my usual monitoring of choice for k8s is Prometheus +
Grafana, but end of the day most of the monitoring solutions do a good job,
so I would mostly ask what do you know the most. For this environments I
would be more interested on proper container management for kafka and
not that I'm aware of, but my experience in the field is really true. it
would be nice to write such article

Hello,
Just curious, is there any article about Java 11 reducing SSL perf impact ?
Thanks,

Hi,
if you're worried about the performance impact i would suggest :
* first benchmark the impacts, by experience i would see around 30 to 40%
performance degradation.
* use java 11, and you will see a lot less performance impact when using
ssl.
