Apache Flink Playgrounds

This repository provides playgrounds to quickly and easily explore Apache Flink's features.

The playgrounds are based on docker-compose environments. Each subfolder of this repository contains the docker-compose setup of a playground, except for the ./docker folder which contains code and configuration to build custom Docker images for the playgrounds.

Available Playgrounds

Currently, the following playgrounds are available:

• The Flink Operations Playground (in the operations-playground folder) lets you explore and play with Flink's features to manage and operate stream processing jobs. You can witness how Flink recovers a job from a failure, upgrade and rescale a job, and query job metrics. The playground consists of a Flink cluster, a Kafka cluster and an example Flink job. The playground is presented in detail in "Flink Operations Playground", which is part of the Try Flink section of the Flink documentation.

• The Table Walkthrough (in the table-walkthrough folder) shows to use the Table API to build an analytics pipeline that reads streaming data from Kafka and writes results to MySQL, along with a real-time dashboard in Grafana. The walkthrough is presented in detail in "Real Time Reporting with the Table API", which is part of the Try Flink section of the Flink documentation.
