---------------------------------------

natengall opened a new pull request #4997: KAFKA-6890: Add connector-level 
configurability for client configs
URL: https://github.com/apache/kafka/pull/4997
 
 
   Introduced capability for individual connectors to override client config 
defaults.
   
   Connector properties that are prefixed with "producer." and "consumer." are 
now used to feed into the producer and consumer clients embedded within source 
and sink connectors respectively.

> Right now, each source connector and sink connector inherit their client 
> configurations from the worker properties. Within the worker properties, all 
> configurations that have a prefix of "producer." or "consumer." are applied 
> to all source connectors and sink connectors respectively.
> We should also provide connector-level overrides whereby connector properties 
> that are prefixed with "producer." and "consumer." are used to feed into the 
> producer and consumer clients embedded within source and sink connectors 
> respectively. The prefixes will be removed via a String#substring() call, and 
> the remainder of the connector property key will be used as the client 
> configuration key. The value is fed directly to the client as the 
> configuration value.
