[jira] [Created] (KAFKA-6020) Broker side filtering

Pavel Micka created KAFKA-6020:
----------------------------------

             Summary: Broker side filtering
                 Key: KAFKA-6020
                 URL: https://issues.apache.org/jira/browse/KAFKA-6020
             Project: Kafka
          Issue Type: Improvement
          Components: consumer
            Reporter: Pavel Micka


Currently, it is not possible to filter messages on broker side. Filtering messages on broker side is convenient for filter with very low selectivity (one message in few thousands). In my case it means to transfer several GB of data to consumer, throw it away, take one message and do it again...

While I understand that filtering by message body is not feasible (for performance reasons), I propose to filter just by message key prefix. This can be achieved even without any deserialization, as the prefix to be matched can be passed as an array (hence the broker would do just array prefix compare).
