Description

This feature is useful for anyone who needs greater control of which partitions are being written to - normally in a situation where multiple Flume agents are being deployed in order to horizontally scale, or alternatively if there is a scenario where there is a skew in data that might lead to one or more partitions hotspotting.

We also have the ability to specify custom partitions on to the Kafka Producer itself using the kafka.* configuration properties.

The Kafka Producer provides the ability to set the partition ID using the following constructor (https://kafka.apache.org/090/javadoc/org/apache/kafka/clients/producer/ProducerRecord.html#ProducerRecord(java.lang.String,%20java.lang.Integer,%20K,%20V%29 ), this is just a matter of providing the option to use this constructor.
