    and to better handle the case where the topic has a single log segment

Minor Version Features

  • Added a broker_version kwarg to Broker.__init__ for the purpose of setting
    api_version in FetchResponse
  • Added a topic_name argument to Broker.join_group for use in protocol metadata,
    visible via the Administrative API

    supports newer message formats
  • Changed Producer.produce to return the produced Message instance
  • Added protocol_version and timestamp kwargs to Message
  • Added support for the fetch_error_backoff_ms kwarg on SimpleConsumer

    that its parent BalancedConsumer is in the process of rebalancing

    user-defined membership protocols to be used

    strategies

  • Fixed a bug causing busywaiting in the BalancedConsumer when there are no partitions
    available
  • Updated the protocol implementation to send non-empty GroupMembershipProtocol
    objects and become compatible with the Administrative API
  • Fixed a bytestring bug causing kafka_tools.reset_offsets not to work in python 3

  • Improved logging on socket errors

  • Fixed a bug causing fetch_offsets not to raise exceptions under certain conditions

  • Adjusted Cluster to become aware of supported API versions immediately upon
    instantiation
  • Refactored code in Cluster related to metadata requests to make logic reusable for
    pre-bootstrap communication with the cluster
  • Added the ability to pass arguments to protocol.Response instances when waiting
    on a future
  • Adjusted the RandomPartitioner to avoid actually calling random.choice to improve
    performance
  • Removed some calls in Producer.procuce to isinstance to improve performance
  • Simplified retry logic in SimpleConsumer.fetch_offsets

Miscellaneous

  • Separated gevent tests from other builds in Travis
  • Made dependency on gevent optional
  • Added a convenient CLI entry point via __main__
  • Fixed exception naming convention to align with naming in the broker
  • Avoided building the rdkafka extension on platforms that don't support it
  • Fixed a bug in test harness causing some tests not to be inherited from parent classes
  • Used sudo: required to get around dead Travis machines
  • Upgraded Travis tests to use Kafka 1.0.0
  • Added Code of Conduct
  • Documented release process
  • Made PyKafka available via conda-forge
  • Fleshed out the beginning of the usage guide
  • Made kafka_instance fetch its binary from archive.apache.org instead of
    mirror.reverse.net because the latter removed old versions of Kafka
