I'm curious as well. That doc blurb doesn't give specifics. How is kafka run (or tested) on Windows? Natively via the command line shell, etc. or via cygwin, within a *nix VM on Windows, or via Windows 10's Ubuntu Linux Bash shell? Would be interesting to see how each method I listed performs, mayb

One issue is that Kafka leverage some very specific features of the linux kernel that are probably far different from Windows, so I imagine the performance profile is likewise much different. On 4/11/17, 8:52 AM, "Tomasz Rojek" wrote: Hi All, We want to choose provider of messagin

Thanks for the feedback. I'm not super familiar with the inner workings of Apache's Maven repos, so I can't explain why we do things the way we do. I followed the same process on all Apache projects I was on (Kafka, Sqoop, Flume). Do you know projects that do things the way you suggested? Either

I updated from 10.1 and 10.2. I updated both the broker and maven dependency. I am using topic auto-create. With 10.1, starting the application with a broker would sometimes result in an error like: > Exception in thread "StreamThread-1" org.apache.kafka.streams.errors.TopologyBuilderException: I

Don't hard code it. Martin's suggestion allows it to be read from a configuration file or injected from another source such as an environment variable at runtime. If you neither of these are acceptable for corporate policy I suggest asking how it has been handled before at your company. Christian

Kafka producer drops large messages

Hello all, Can somebody shed light on kafka producer's behavior when the total size of all messages in the buffer (bounded by queue.buffering.max.ms) exceeds the socket buffer size (send.buffer.bytes)? I'm using Kafka v0.8.2 with the old Producer API and have noticed that our systems are dropping

Thanks for the clarification Matthais / Michael! +1 to clear documentation around this because as far as I remember, default for normal consumers is "latest" and since Streams internally use normal consumers, the first intuition is that it will be "latest" for Streams as well. Best, Mahendra

It's also documented at http://docs.confluent.io/current/streams/developer-guide.html#non-streams-configuration-parameters . FYI: We have already begun syncing the Confluent docs for Streams into the Apache Kafka docs for Streams, but there's still quite some work left (volunteers are welcome :-P)
