I just resolved the fix I needed before having time to see your reply. I took all references to JsonPOJO and Jackson JSON dependencies and am using for VALUE_SERDE_CONFIG SpecificAvroSerde and it works well. Indeed I had not planned to embed the schema info in each message as this would be tedious

The examples code in AK repo uses JSON as the serde, whereas the examples in CP repo used Avro, with the embedded schema. These two are different serde schemes. Using a schema registry for Avro / etc would be a better approach to you, since it does not require each message to embed the schema info

I think I should simply follow Kafka The Definitive Guide Chapter 3 for a good Avro producer example instead. It does not introduce some Jackson JSON layer and still provides the type safety using POJO generated classes from Avro. On Wed, Jul 6, 2016 at 9:20 PM, Philippe Derome wrote: > The type

The typed version of the example (PageViewTypedDemo) is what represents some difficulty for someone new to Kafka (or CP3). *I think it would be easier/quicker to complete the documentation of that example than to answer my questions below* I am reusing the same JsonPOJOSerializer and JsonPOJOD

yes, it's a very similar example and I am interested in the Kafka one for the serialization aspect of it, which is a bit richer than on Confluent's... On Wed, Jul 6, 2016 at 5:35 AM, Michael Noll wrote: > Correction: Just realized that I misread your message. You are indeed > referring to the

Phil, I suggest to ask this question in the Confluent Platform mailing list because you're referring to code under https://github.com/confluentinc/examples (i.e. code that is not part of the Apache Kafka project). Best, Michael On Tue, Jul 5, 2016 at 5:34 PM, Philippe Derome wrote: > Would an

Would anyone with a good understanding of serialization be available to enhance documentation of the Apache Streams examples? I mean specifically: PageViewTypedDemo, PageViewUntypedDemo in package org .apache.kafka.streams.examples.pageview I'd be happy to run them with Confluent Platform 3 produc
