Summary: Filter-plugins for messages
Key: KAFKA-1448
URL: https://issues.apache.org/jira/browse/KAFKA-1448
Project: Kafka
Issue Type: Wish
Components: consumer
Reporter: Moritz Möller
Assignee: Neha Narkhede
Hi,
we use Kafka to transmit different events that occur on different products, and
would like to be able to subscribe only to a certain set of events for certain
products.
Using one topic for each event * product combination would yield around 2000
topics, which seems to be not what kafka is designed for.
What we would need is a way to add a consumer filter plugin to kafka (a simple
class that can accept or reject a message) and to pass a parameter from the
consumer to that filter class.
Is there a better way to do this already, or if not, would you accept a patch
upstream that adds such a mechanism?
Thanks,
Mo
