# cppkafka
---
High level C++ wrapper for _rdkafka_
---
# Features
* _cppkafka_ is a high level C++ wrapper for _rdkafka_, aiming at allowing to use _rdkafka_ in a
simple, less error prone way.
* _cppkafka_ provides an API to produce messages as well as consuming messages, but the latter is
only supported via the high level consumer API. _cppkafka_ requires **rdkakfa >= 0.9.4** in
order to use it. Other wrapped functionalities are also provided, like fetching metadata,
offsets, etc.
**Note**: _cppkafka_ is under development so the API might change through time. Once there's an
actual release, it should become more stable.
# It's simple!
_cppkafka_'s API is simple. For example, this code creates a producer writes a message into some
partition:
```c++
#include <cppkafka/producer.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));
}
```
# Compiling
In order to compile _cppkafka_ you need:
* _rdkafka >= 0.9.4_
* _CMake_
* A compiler with good C++11 support (e.g. gcc >= 4.8). This was tested successfully on
_g++ 4.8.3_.
* The boost library. _cppkafka_ only requires boost.optional, which is a header only library,
so this doesn't add any additional runtime dependencies.
Now, in order to build, just run:
```Shell
mkdir build
cd build
cmake ..
make
```
# Using
If you want to use _cppkafka_, you'll need to link your application with:
* _cppkafka_
* _rdkafka_
# Documentation
You can generate the documentation by running `make docs` inside the build directory. This requires
_Doxygen_ to be installed. The documentation will be written in html format at
`<build-dir>/docs/html/`.
