cppkafka

To compile cppkafka from source, ensure you have the following dependencies installed:

• librdkafka >= 0.9.4
• CMake >= 3.9.2
• A C++11 compatible compiler (e.g., gcc >= 4.8)
• The Boost library (specifically for boost::optional)

Follow these steps to build and install:

mkdir build
cd build
cmake <OPTIONS> ..
make
make install

You can generate HTML documentation for cppkafka using Doxygen. Run the following command from within your build directory:

make docs

The resulting documentation will be located at <build-dir>/docs/html/.

To use cppkafka in your own application, you must link against both cppkafka and rdkafka. If you are using CMake, you can simplify this by using find_package and linking to the CppKafka::cppkafka target.

find_package(CppKafka REQUIRED)

target_link_libraries(<YourLibrary> CppKafka::cppkafka)

To send messages to a Kafka topic, use the Configuration class to set broker details and the Producer class to send the data. The MessageBuilder is used to construct the message, allowing you to specify the topic, partition, and payload.

#include <cppkafka/cppkafka.h>

using namespace std;
using namespace cppkafka;

int main() {
    // Create the config
    Configuration config = {
        { "metadata.broker.list", "127.0.0.1:9092" }
    };

    // Create the producer
    Producer producer(config);

    // Produce a message!
    string message = "hey there!";
    producer.produce(MessageBuilder("my_topic").partition(0).payload(message));
    producer.flush();
}
