Kafka

Hi Kafka users, We are a 1000 people governemental french organization, willing to use Apache Kafka to integrate our applications. We currently use Talend ETL for that purpose. We are developing a prototype on Apache Kafka 4.0, Kraft mode, which seems to fulfill our needs until now. Our request : we would like to have some feedbacks about using Apache Kafka in small organizations like ours - let's say, less than 5000 people : for what purpose it is used in your organization, what are the resources and tools needed for the run, main technical issues or tricky things to take care, etc. Best regards, Olivier Dexheimer Architecture & Devs Information Systems Management GrandPalaisRmn

I used the staged binaries and Maven artifacts ... and did some manual smoke testing and tested it with Strimzi tests as well. All seems to work fine, so +1 (non-binding).
