Init python virtual environment

python -m venv .env/data-engineering

Activate python virtual environment

source .env/data-engineering/bin/activate

Some of the projects are using different versions of java and scala, so it is recommended to use SDKMAN to manage the versions of java and scala.

Install SDKMAN

curl -s "https://get.sdkman.io" | bash

Then you can run the following command in proper project directory to install the latest version of java and scala

sdk env install 

The custom partitioner for the Kafka Connect S3 Sink connector requires a JDK 11. You can install it using SDKMAN The scala projects of Apache Flink job require JDK 17 and Scala 2.12.19

Please check the .sdkmanrc file in the root of the project to see the versions of java and scala required for each project.

The docker compose file is located in the data-engineering-tools of the project. You can start the environment using the following command:

docker compose up -d zookeeper kafka schema-registry minio kafkactl redpanda-console kconnect-s3sink awscli minio-client

The command above will start the the environment for the testing Kafka Connect S3 Sink connector and other goodies like minio, redpanda, kafkactl, etc.

To start the environment for the Apache Flink project, you can run similar but excuding the kconnect-s3sink service.

The important part is the configure a connector for the Kafka Connect S3 Sink. You can use the Insonmia or Postman to send a POST request to the Kafka Connect REST API to create a connector. The connector configuration is located in the data-engineering-tools/kafka-connect directory of the project, the filename is Insomnia_*.json.
