Hello
I tried what you told me too, but I already have the tools-log4j.properties set
to WARN, and I don't have a variable KAFKA_LOG4J_OPTS set. I even tried to
disable all the logs, but the same happens.
It's not that the Kafka doesn't work because it works, but it shows to much
info. Could
Hi all,
We are debugging an issue with a Kafka Streams application that is producing
incorrect output. The application is a simple group-by on a key, and then
count. As expected, the application creates a repartitioning topic for the
group-by stage. The problem appears to be that messages are g
Follow-up: I think we figured out what was happening. Setting the broker config
log.message.timestamp.type=LogAppendTime (instead of the default value
CreateTime) stopped the messages disappearing.
The messages in the Streams app's input topic are older than the 24 hours
default retention perio
Hi, Andrew.
The Converter is part of Connect's public API, so it certainly is
valid/encouraged to create new implementations when that makes sense for
users. I know of several Converter implementations that are outside of the
Apache Kafka project. The project's existing JSON converter is fairly

Hi everyone
I have design an integration between 2 systems throug our API Stream Kafka,
and the requirements are unclear to choose properly the number of
partitions/topics.
That is the use case:
My producer will send 28 different type of events, so I have decided to
create 28 topics.
The max si
Hi Srikanth,
How did you set the LogAndContinueExceptionHandler in the configs? Could
you copy the code snippet here?

Hello Martin,
What you've observed is correct. More generally speaking, for various
broker-side operations that based on record timestamps and treating them as
wall-clock time, there is a mismatch between the stream records' timestamp
which is basically "event time", against the broker's system wa
Hi all,
The following post I wrote describes the usage of change-data-capture and
Kafka for user behavior analysis, connecting database record changes to
user context in near real-time.

so it goes beyond the throughput that kafka can support. You have to decide as
to what degree of parallelism your application can support. If one message
processing depends on processing for another message, that limits the degree to
which you can process in parallel. Depending on how much time
Hi All,
I was experimenting on the new consumer API and have a question regarding
the rebalance process.
I start a consumer group with single thread and make the Thread sleep while
processing the records retrieved from the first consumer.poll call, i was
making sure the Thread.sleep time goes bey
We're using 0.9 ( CDH ) and consumer offsets are stored within Kafka. What
is the preferred way to get consumer offset from code or script for
monitoring ? Is there any sample code/ script to do so ?
Thanks,

Hello -
The above API gives me the range of values between fromKey and toKey for a
local state store.
Suppose I have an application running in distributed mode (multiple nodes
same application id). How does this API translate to multiple nodes ? I
know the basic implementation is for a local nod
