## Purpose

The Kafka Processor `CØSMOS-Block` is basically a Stream Processor which continuously

reads [CØSMOS blocks](https://docs.cosmos.network/master/intro/sdk-app-architecture.html) from an `input` Kafka topic,

unwraps the CØSMOS transactions and sends them to an `output` topic.



  



This processor plays well with the [CØSMOS Kafka Connector](https://github.com/okp4/kafka-connector-cosmos)

which provides Kafka with CØSMOS blocks ready to be processed.

## Implementation

Implementation mainly relies on [Kafka Streams API](https://kafka.apache.org/documentation/streams), library to create

event-stream applications with the following features:

- no external dependency other than Kafka itself,

- simple and light library,

- fault-tolerant and scalable.

Moreover, this implementation:

- uses [Kotkin](https://kotlinlang.org/) as primary coding language,

- uses [Quarkus](https://quarkus.io/) to minimize resources consumption,

- is as much as possible, lean, i.e. tries to minimize the dependencies to 3rd party libraries and the resulting package

  footprint.

## Build

This project targets the [JVM 11+](https://openjdk.java.net/), so be sure to have it available in your environment.

This project relies on the [Gradle](https://gradle.org/) build system.

If you are on Windows then open a command line, go into the root directory and run:

```sh

.\gradlew build

```

If you are on linux/mac then open a terminal, go into the root directory and run:

```sh

./gradlew build

```

This command line produces a _native_ executable: `kafka-processor-cosmos-block-X.Y-runner`
