pykafka - Apache Kafka client for Python; high-level & low-level consumer/producer, with great performance

•    Python

---

PyKafka is a cluster-aware Kafka>=0.8.2 client for Python. It includes Python implementations of Kafka producers and consumers, which are optionally backed by a C extension built on librdkafka, and runs under Python 2.7+, Python 3.4+, and PyPy.PyKafka's primary goal is to provide a similar level of abstraction to the JVM Kafka client using idioms familiar to Python programmers and exposing the most Pythonic API possible.

ruby-kafka - A Ruby client library for Apache Kafka

•    Ruby

---

A Ruby client library for Apache Kafka, a distributed log and message bus. The focus of this library will be operational simplicity, with good logging and metrics that can make debugging issues easier.Although parts of this library work with Kafka 0.8 – specifically, the Producer API – it's being tested and developed against Kafka 0.9. The Consumer API is Kafka 0.9+ only.

kafka-python - Python client for Apache Kafka

•    Python

---

Python client for the Apache Kafka distributed stream processing system. kafka-python is designed to function much like the official java client, with a sprinkling of pythonic interfaces (e.g., consumer iterators).kafka-python is best used with newer brokers (0.9+), but is backwards-compatible with older versions (to 0.8.0). Some features will only be enabled on newer brokers. For example, fully coordinated consumer groups -- i.e., dynamic partition assignment to multiple consumers in the same group -- requires use of 0.9+ kafka brokers. Supporting this feature for earlier broker releases would require writing and maintaining custom leadership election and membership / health check code (perhaps using zookeeper or consul). For older brokers, you can achieve something similar by manually assigning different partitions to each consumer instance with config management tools like chef, ansible, etc. This approach will work fine, though it does not support rebalancing on failures. See <https://kafka-python.readthedocs.io/en/master/compatibility.html> for more details.

CSharpClient-for-Kafka -

•    CSharp

---

This library was created for Kafka 0.8 with an intention to have a native library built from scratch. With Kafka protocol getting updated frequently with new features (which is expected until it reaches version 1.0), it doesn't seem beneficial to maintain a library built from scratch. The right approach (and as suggested by Confluent) for now would be to use a C# wrapper around the librdkafka C-Library, which the confluent-kafka-dotnet client is doing.So, if you are using Kafka 0.9 or higher, please move to using the confluent-kafka-dotnet client library.

kafkacat is a generic non-JVM producer and consumer for Apache Kafka >=0.8, think of it as a netcat for Kafka.In producer mode kafkacat reads messages from stdin, delimited with a configurable delimiter (-D, defaults to newline), and produces them to the provided Kafka cluster (-b), topic (-t) and partition (-p).

kafka-go - Kafka library in Go

•    Go

---

sarama, which is by far the most popular but is quite difficult to work with. It is poorly documented, the API exposes low level concepts of the Kafka protocol, and it doesn't support recent Go features like contexts. It also passes all values as pointers which causes large numbers of dynamic memory allocations, more frequent garbage collections, and higher memory usage. confluent-kafka-go is a cgo based wrapper around librdkafka, which means it introduces a dependency to a C library on all Go code that uses the package. It has much better documentation than sarama but still lacks support for Go contexts.

alpakka-kafka - Alpakka Kafka connector - Alpakka is a Reactive Enterprise Integration library for Java and Scala, based on Reactive Streams and Akka

•    Scala

---

Systems don't come alone. In the modern world of microservices and cloud deployment, new components must interact with legacy systems, making integration an important key to success. Reactive Streams give us a technology-independent tool to let these heterogeneous systems communicate without overwhelming each other. The Alpakka project is an open source initiative to implement stream-aware, reactive, integration pipelines for Java and Scala. It is built on top of Akka Streams, and has been designed from the ground up to understand streaming natively and provide a DSL for reactive and stream-oriented programming, with built-in support for backpressure. Akka Streams is a Reactive Streams and JDK 9+ java.util.concurrent.Flow-compliant implementation and therefore fully interoperable with other implementations.
