We’ve been playing with Druid for quite a while now. It is GREAT.
Now we are playing with the realtime ingestion part of Druid. And unfortunately, there are different types of messages with completely different schema in some topics of Kafka. So I’m wondering what is the best practice for Druid to (1) filter/split the Kafka json stream so that we can read only the message we want? (2) flat nested json?
