  • v1.7.0 Changes

    👀 confluent-kafka-go is based on librdkafka v1.7.0, see the 🚀 librdkafka release notes ⬆️ for a complete list of changes, enhancements, fixes and upgrade considerations.

    ✨ Enhancements

    • Experimental Windows support (by @neptoess).
    • The produced message headers are now available in the delivery report Message.Headers if the Producer's go.delivery.report.fields configuration property is set to include headers, e.g.: "go.delivery.report.fields": "key,value,headers" This comes at a performance cost and are thus disabled by default.

    🛠 Fixes

    • 0️⃣ AdminClient.CreateTopics() previously did not accept default value(-1) of ReplicationFactor without specifying an explicit ReplicaAssignment, this is now fixed.

  • v1.6.1 Changes

    🚀 v1.6.1 is a feature release:

    • KIP-480: Sticky producer partitioner - increase throughput and decrease latency by sticking to a single random partition for some time.
    • KIP-447: Scalable transactional producer - a single transaction producer can now be used for multiple input partitions.

    👀 confluent-kafka-go is based on and bundles librdkafka v1.6.1, see the 🚀 librdkafka release notes ⬆️ for a complete list of changes, enhancements, fixes and upgrade considerations.

    ✨ Enhancements

    • go.delivery.report.fields=all,key,value,none can now be used to avoid copying message key and/or value to the delivery report, improving performance in high-throughput applications (by @kevinconaway).

    🛠 Fixes

    • Consumer.Close() previously did not trigger the final RevokePartitions callback, this is now fixed.

      • System root CA certificates should now be picked up automatically on most platforms
      • Fix produce/consume hang after partition goes away and comes back,
        such as when a topic is deleted and re-created (regression in v1.3.0).

    librdkafka v1.4.2 changes

    🚀 See the librdkafka v1.4.2 release notes for changes to the bundled librdkafka included with the Go client.

  • v1.4.0 Changes

    April 08, 2020

    confluent-kafka-go v1.4.0

    • Added Transactional Producer API and full Exactly-Once-Semantics (EOS) support.
    • A prebuilt version of the latest version of librdkafka is now bundled with the confluent-kafka-go client. A separate installation of librdkafka is NO LONGER REQUIRED or used.
    • ➕ Added support for sending client (librdkafka) logs to Logs() channel.
    • ➕ Added Consumer.Position() to retrieve the current consumer offsets.
    • The Error type now has additional attributes, such as IsRetriable() to deem if the errored operation can be retried. This is currently only exposed for the Transactional API.
    • ✂ Removed support for Go < 1.9

    Transactional API

    🚀 librdkafka and confluent-kafka-go now has complete Exactly-Once-Semantics (EOS) functionality, supporting the idempotent producer (since v1.0.0), a transaction-aware consumer (since v1.2.0) and full producer transaction support (in this release).
    This enables developers to create Exactly-Once applications with Apache Kafka.

    👀 See the Transactions in Apache Kafka page for an introduction and check the transactions example for a complete transactional application example.

    Bundled librdkafka

    The confluent-kafka-go client now comes with batteries included, namely prebuilt versions of librdkafka for the most popular platforms, you will thus no longer need to install or manage librdkafka separately.

    👌 Supported platforms are:

    • Mac OSX
    • 🐧 glibc-based Linux x64 (e.g., RedHat, Debian, etc) - lacks Kerberos/GSSAPI support
    • 🐧 musl-based Linux x64 (Alpine) - lacks Kerberos/GSSAPI support

    🐧 These prebuilt librdkafka has all features (e.g., SSL, compression, etc) except for the Linux builds which due to libsasl2 dependencies does not have Kerberos/GSSAPI support.
    🏗 If you need Kerberos support, or you are running on a platform where the prebuilt librdkafka builds are not available (see above), you will need to install librdkafka separately (preferably through the Confluent APT and RPM repositories) and build your application with -tags dynamic to disable the builtin librdkafka and instead link your application dynamically to librdkafka.
