Motivation

The StreamsResetter doesn't let the user pass in any configurations to the embedded consumer. This is a problem in secure environments because you can't configure the embedded consumer to talk to the cluster. The streams reset tool should allow an approach to pass consumer configurations. There are 2 options.

Public Interfaces

To add 2 options to StreamsReset tool.

consumerPropertyOption = optionParser.accepts("consumer-property", "A mechanism to pass user-defined properties in the form key=value to the consumer")
        .withRequiredArg()
        .ofType(String.class)
        .describedAs("consumer property");
 
consumerConfigOption = optionParser.accepts("consumer.config", "Consumer configuration properties file, Note that " + consumerPropertyOption.toString() + " takes precedence over this config")
        .withRequiredArg()
        .ofType(String.class)
        .describedAs("Consumer config property file");
 

Proposed Changes

To add 2 options to streams reset tool.

1. consumer.config - To pass consumer configuration properties file.
2. consumer-property - To pass consumer property as a key=value pair

Compatibility, Deprecation, and Migration Plan

• • This is purely an addition of an option to kafka-streams-application-reset.sh. It will not cause any compatibility issues.

Rejected Alternatives

No rejected alternatives. As without the config options, streams reset tool will not work in Secure Kafka cluster
