librdkafka is a C library implementation of the Apache Kafka protocol, containing both Producer and Consumer support. It was designed with message delivery reliability and high performance in mind, current figures exceed 1 million msgs/second for the producer and 3 million msgs/second for the consumer.

librdkafka is licensed under the 2-clause BSD license.

For an introduction to the performance and usage of librdkafka, see INTRODUCTION.md

See the wiki for a FAQ.

NOTE: The master branch is actively developed, use latest release for production use.
