Hi Damian, The rest of the logs were INFO messages about offset being committed. Anyways, the problem is resolved for now, after we increased the max.poll.interval.ms. For anyone else who is facing similar problem, please refer this thread. https://groups.google.com/forum/#!topic/confluent-platf

To test Kafka streams on 0.10.2.0, we setup a new Kafka cluster with the latest version and used mirror maker to replicate the data from the 0.10.0.0 Kafka cluster. We pointed our streaming app to the newly created Kafka cluster. We have 5 nodes, each running the streaming app with 10 threads. In

Hi Mahendra, Just a kind reminder that upgrading Streams to 0.10.2 does not necessarily require you to upgrade brokers to 0.10.2 as well. Since we have added a new feature since 0.10.2 to allow newer versioned clients (producer, consumer, streams) to talk to older versioned brokers, and for Stream

We are planning to migrate to the newer version of Kafka. But that's a few weeks away. We will try setting the socket config and see how it turns out. Thanks a lot for your response! On Mon, Mar 13, 2017 at 3:21 PM, Eno Thereska wrote: > Thanks, > > A couple of things: > - I’d recommend movi

Thanks, A couple of things: - I’d recommend moving to 0.10.2 (latest release) if you can since several improvements were made in the last two releases that make rebalancing and performance better. - When running on environments with large latency on AWS at least (haven’t tried Google cloud), o

Capacity planning for Kafka Streams

2017-03-12 Thread Mahendra Kariya
Hey All, Are there some guidelines / documentation around capacity planning for Kafka streams? We have a Streams application which consumes messages from a topic with 400 partitions. At peak time, there are around 20K messages coming into that topic per second. The Streams app consumes these
