Hi Jay,

I used to play with kafka, ported librdkafka library to IBMi, see here: https://github.com/AlexeiBaranov/librdkafka. One of our customers uses kafka in production environment. The kafka server itself is on a Linux cluster next to IBMi. Native RPGLE clients and consumers run on IBMi, using librdkafka library - they use my port, although they themselves have already updated library to the latest version.

Regards,
Alexei

Is there anyone here that has Kafka installed and running on IBM I and serving native applications such as RPG and or COBOL?

The only reference I can find at all close to IBM I architecture is on ibm i oss yet it only explains how to install. Much less configure and utilize from a native standpoint.
And when I say native I’m talking about traditional ibm i architecture relevant typical of iseries and AS/400.
Not PASE and open source although I realize this is the area where Kafka runs.

We’ve managed to download and install and get a Kafka server up and running but not much more.

I do also have a consumer api using db2 sql http_post to stream some data to the server and the server.log does log this activity when it’s invoked but sadly in the form of an error msg. I picked this api example up in the past in which I honestly cannot even recall from where. I’m guessing Jesse G’s GitHub but I cannot find it on there presently.

We have no idea where to go to get this working.

Any suggestions or guidance would be greatly appreciated.

Thanks

Jay V
