Stephen, There is a mailing list for kafka client developers that you may find useful: https://groups.google.com/forum/#!forum/kafka-clients
The d...@kafka.apache.org<mailto:d...@kafka.apache.org> mailing list might also be a good resource: http://kafka.apache.org/contact.html Lastly, do you have any way to do HTTP calls on your platform? There exist some REST servers that you speak HTTP to and then they will produce to Kafka on your behalf. Here is one: http://docs.confluent.io/2.0.1/kafka-rest/docs/index.html -James On Mar 3, 2016, at 2:47 AM, Hopson, Stephen <stephen.hop...@gb.unisys.com<mailto:stephen.hop...@gb.unisys.com>> wrote: Hi, Not sure if this is the right forum for this question, but if it not I’m sure someone will direct me to the proper one. Also, I am new to Kafka (but not new to computers). I want to write a kafka producer client for a Unisys OS 2200 mainframe. I need to write it in C, and since I have no access to Windows / Unix / Linux libraries, I have to develop the interface at the lowest level. So far, I have downloaded a kafka server with associated zookeeper (kafka _2.10-0.8.2.2). Note I have downloaded the Windows version and have it running on my laptop, successfully tested on the same laptop with the provided provider and consumer clients. I have developed code to open a TCP session to the kafka server which appears to work and I have attempted to send a metadata request which does not appear to work. When I say it does not appear to work, I mean that I send the message and then I sit on a retrieve, which eventually times out ( I do seem to get one character in the receive buffer of 0235 octal). The message format I am using is the one described by the excellent document by Jay Creps / Gwen Shapira athttps://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol However, it is not clear what level of kafka these message formats are applicable for. Can anybody offer me any advice or suggestions as to how to progress? PS is the CRC mandatory in the Producer messages? Many thanks in advance.
