Motivation

When using the Kafka command-line tools to do simple performance tests, it quickly becomes evident that kafka-producer-perf-test.sh  and the equivalent consumer tools do not follow the same conventions for command-line arguments. Strangely, kafka-producer-perf-test.sh  does not support the --bootstrap-server  argument which all of the other tools do, instead requiring --producer.props bootstrap.servers= (note the "s" on "bootstrap.servers" because it's the name of the producer config). This means that simple familiarity with the other tools isn't sufficient to get the command line for this tool correct without a little trial and error.

There are a few other inconsistencies where different names are used for the same thing in different toolsDescribe the problems you are trying to solve.

Public Interfaces

Briefly list any new interfaces that will be introduced as part of this proposal or any existing interfaces that will be removed or changed. The purpose of this section is to concisely call out the public contract that will come along with this feature.

...

  • Binary log format

  • The network protocol and api behavior

  • Any class in the public packages under clientsConfiguration, especially client configuration

    • org/apache/kafka/common/serialization

    • org/apache/kafka/common

    • org/apache/kafka/common/errors

    • org/apache/kafka/clients/producer

    • org/apache/kafka/clients/consumer (eventually, once stable)

  • Monitoring

  • Command line tools and arguments

  • Anything else that will likely break existing users in some way when they upgrade

The proposed changes are:

  • Add --bootstrap-server  to kafka-producer-perf-test.sh  bringing it into line with all the other tools
  • Replace --producer-props  with --producer-properties  in kafka-producer-perf-test.sh , bringing it into line with the other tools that accept producer or consumer properties
  • For all tools, with the exception of those which support either --producer-properties  or --consumer-properties , replace the existing option for specifying a configuration properties file with --command-config
