Database Trigger in Druid


We are evaluating Druid for a real-time ingestion use case. After ingestion, we want to invoke a custom function on the rolled up row and post a message to Kafka.

I was wondering if Druid supports trigger.

Or, should we follow a different design pattern?



Hey Shah,

Druid doesn’t support that kind of thing. Would it make sense to do the trigger using a stream processor before the data gets into Druid?
