[jira] [Created] (FLINK-6288) FlinkKafkaProducer's custom Partitioner is always invoked with number of partitions of default topic

Tzu-Li (Gordon) Tai created FLINK-6288:
------------------------------------------

             Summary: FlinkKafkaProducer's custom Partitioner is always invoked with number of partitions of default topic
                 Key: FLINK-6288
                 URL: https://issues.apache.org/jira/browse/FLINK-6288
             Project: Flink
          Issue Type: Improvement
          Components: Kafka Connector
            Reporter: Tzu-Li (Gordon) Tai


The {{FlinkKafkaProducerBase}} supports routing records to topics besides the default topic, but the custom {{Partitioner}} interface does not follow this semantic.

The partitioner is always invoked the {{partition}} method with the number of partitions in the default topic, and not the number of partitions of the current {{targetTopic}}.
