------------------------------------
Summary: Make config and config defaults accessible to clients
Key: KAFKA-1794
URL: https://issues.apache.org/jira/browse/KAFKA-1794
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.1.1
Reporter: Navina Ramesh
In the new Kafka producer API, the ProducerConfig is not accessible to the
clients. Samza uses the ProducerConfig instance to access the defaults property
values, which can then be used in the various helper utils. Config instance is
accessible even without instantiating a Kafka producer.
With the new API, there is no way to instantiate a ProducerConfig as the
constructor is marked private. Also, it does not make the default config values
accessible to the client without actually instantiating a KafkaProducer.
Changes suggested:
1. Make the ProducerConfig constructor public
2. Make ConfigDef in ProducerConfig accessible by the client
3. Use public static variables for kafka config default "values"
