Akka
====
*Akka is a powerful platform that simplifies building and operating highly responsive, resilient, and scalable services.*


The platform consists of
* the [**Akka SDK**](https://doc.akka.io/java/index.html) for straightforward, rapid development with AI assist and automatic clustering. Services built with the Akka SDK are automatically clustered and can be deployed on any infrastructure.
* and [**Akka Automated Operations**](https://doc.akka.io/operations/akka-platform.html), a managed solution that handles everything for Akka SDK services from auto-elasticity to multi-region high availability running safely within your VPC.

The **Akka SDK** and **Akka Automated Operations** are built upon the foundational [**Akka libraries**](https://doc.akka.io/libraries/akka-dependencies/current/), providing the building blocks for distributed systems.

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](https://doc.akka.io/libraries/akka-core/current/stream/index.html), 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](https://www.reactive-streams.org/) and JDK 9+ [java.util.concurrent.Flow](https://docs.oracle.com/javase/10/docs/api/java/util/concurrent/Flow.html)-compliant implementation and therefore [fully interoperable](https://doc.akka.io/libraries/akka-core/current/general/stream/stream-design.html#interoperation-with-other-reactive-streams-implementations) with other implementations.

This repository contains the sources for the **Alpakka Kafka connector**. Which lets you connect [Apache Kafka](https://kafka.apache.org/) to Akka Streams. It was formerly known as **Akka Streams Kafka** and even **Reactive Kafka**.

Akka Stream connectors to other technologies are listed in the [Alpakka repository](https://github.com/akka/alpakka).


## Build Token

To build locally, you need to fetch a token at https://account.akka.io/token that you have to place into `~/.sbt/1.0/akka-commercial.sbt` file like this:
```
ThisBuild / resolvers += "lightbend-akka".at("your token resolver here")
```
