librdkafka - the Apache Kafka C/C++ client library
Copyright (c) 2012-2020, Magnus Edenhill.
librdkafka is a C library implementation of the
Apache Kafka protocol, providing Producer, Consumer
and Admin clients. 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.

has been licensed for use by librdkafka. librdkafka has no
affiliation with and is not endorsed by The Apache Software Foundation.

Installation
Installing prebuilt packages
On Mac OSX, install librdkafka with homebrew:
$brew installlibrdkafka
On Debian and Ubuntu, install librdkafka from the Confluent APT repositories,
see instructions here and then install librdkafka:
$apt installlibrdkafka-dev
On RedHat, CentOS, Fedora, install librdkafka from the Confluent YUM repositories,
instructions here and then install librdkafka:
$yum installlibrdkafka-devel
On Windows, reference librdkafka.redist NuGet package in your Visual Studio project.
For other platforms, follow the source building instructions below.
Installing librdkafka using vcpkg
You can download and install librdkafka using the vcpkg dependency manager:
# Install vcpkg if not already installed
$git clone https://github.com/Microsoft/vcpkg.git
$cdvcpkg
$./bootstrap-vcpkg.sh
$./vcpkg integrate install
# Install librdkafka
$vcpkg installlibrdkafka
The librdkafka package in vcpkg is kept up to date by Microsoft team members and community contributors.
If the version is out of date, please create an issue or pull request on the vcpkg repository.
Build from source
Requirements
The GNU toolchain
GNU make
pthreads
zlib-dev (optional, for gzip compression support)
libssl-dev (optional, for SSL and SASL SCRAM support)
libsasl2-dev (optional, for SASL GSSAPI support)
libzstd-dev (optional, for ZStd compression support)
NOTE: Static linking of ZStd (requires zstd >= 1.2.1) in the producer
enables encoding the original size in the compression frame header,
which will speed up the consumer.
Use STATIC_LIB_libzstd=/path/to/libzstd.a ./configure --enable-static
to enable static ZStd linking.
MacOSX example:
STATIC_LIB_libzstd=$(brew ls -v zstd | grep libzstd.a$) ./configure --enable-static
Building
./configure
# Or, to automatically install dependencies using the system's package manager:
# ./configure --install-deps
# Or, build dependencies from source:
# ./configure --install-deps --source-deps-only
make
sudo make install
NOTE: See README.win32 for instructions how to build
on Windows with Microsoft Visual Studio.
NOTE: See CMake instructions for experimental
CMake build (unsupported).
Usage in code
Refer to the examples directory for code using:
Producers: basic producers, idempotent producers, transactional producers.
Consumers: basic consumers, reading batches of messages.
Performance and latency testing tools.
Refer to the examples GitHub repo for code connecting to a cloud streaming data service based on Apache Kafka
Link your program with -lrdkafka (C) or -lrdkafka++ (C++).
