1.0.0 (Feb 15, 2016)

This release includes significant code changes. Users of older kafka-python versions are encouraged to test upgrades before deploying to production as some interfaces and configuration options have changed.

Users of SimpleConsumer / SimpleProducer / SimpleClient (formerly KafkaClient) from prior releases should migrate to KafkaConsumer / KafkaProducer. Low-level APIs (Simple*) are no longer being actively maintained and will be removed in a future release.

For comprehensive API documentation, please see python help() / docstrings, kafka-python.readthedocs.org, or run ‘tox -e docs’ from source to build documentation locally.

Consumers

  • KafkaConsumer re-written to emulate the new 0.9 kafka consumer (java client) and support coordinated consumer groups (feature requires >= 0.9.0.0 brokers)
    • Methods no longer available:
      • configure [initialize a new consumer instead]
      • set_topic_partitions [use subscribe() or assign()]
      • fetch_messages [use poll() or iterator interface]
      • get_partition_offsets
      • offsets [use committed(partition)]
      • task_done [handled internally by auto-commit; or commit offsets manually]
    • Configuration changes (consistent with updated java client):
      • lots of new configuration parameters – see docs for details
      • auto_offset_reset: previously values were ‘smallest’ or ‘largest’, now values are ‘earliest’ or ‘latest’
      • fetch_wait_max_ms is now fetch_max_wait_ms
      • max_partition_fetch_bytes is now max_partition_fetch_bytes
      • deserializer_class is now value_deserializer and key_deserializer
      • auto_commit_enable is now enable_auto_commit
      • auto_commit_interval_messages was removed
      • socket_timeout_ms was removed
      • refresh_leader_backoff_ms was removed
  • SimpleConsumer and MultiProcessConsumer are now deprecated and will be removed in a future release. Users are encouraged to migrate to KafkaConsumer.

Producers

  • new producer class: KafkaProducer. Exposes the same interface as official java client. Async by default; returned future.get() can be called for synchronous blocking
  • SimpleProducer is now deprecated and will be removed in a future release. Users are encouraged to migrate to KafkaProducer.

Clients

  • synchronous KafkaClient renamed to SimpleClient. For backwards compatibility, you will get a SimpleClient via ‘from kafka import KafkaClient’. This will change in a future release.
  • All client calls use non-blocking IO under the hood.
  • Add probe method check_version() to infer broker versions.

Documentation

  • Updated README and sphinx documentation to address new classes.
  • Docstring improvements to make python help() easier to use.

Internals

  • Old protocol stack is deprecated. It has been moved to kafka.protocol.legacy and may be removed in a future release.
