v2.12.0 - 2025-10-09

v2.12.0 is a feature release with the following enhancements:

KIP-848 – General Availability

Starting with confluent-kafka-python 2.12.0, the next generation consumer group rebalance protocol defined in KIP-848 is production-ready. Please refer to the following migration guide for moving from classic to consumer protocol.

Note: The new consumer group protocol defined in KIP-848 is not enabled by default. There are few contract change associated with the new protocol and might cause breaking changes. group.protocol configuration property dictates whether to use the new consumer protocol or older classic protocol. It defaults to classic if not provided.

AsyncIO Producer (experimental)

Introduces beta class AIOProducer for asynchronous message production in asyncio applications.

Added

• AsyncIO Producer (experimental): Introduces beta class AIOProducer for asynchronous message production in asyncio applications. This API offloads blocking librdkafka calls to a thread pool and schedules common callbacks (error_cb, throttle_cb, stats_cb, oauth_cb, logger) onto the event loop for safe usage inside async frameworks.

Features

• Batched async produce: await AIOProducer(...).produce(topic, value=...) buffers messages and flushes when the buffer threshold or timeout is reached.
• Async lifecycle: await producer.flush(), await producer.purge(), and transactional operations (init_transactions, begin_transaction, commit_transaction, abort_transaction).

Limitations
