| <h2>Hello Beam Pipeline</h2> |
| <p> |
| Apache Beam is an open source, unified model for defining both batch and streaming data-parallel |
| processing pipelines. Using one of the open source Beam SDKs, you build a program that defines the |
| pipeline. The pipeline is then executed by one of Beam’s supported distributed processing |
| back-ends, which include Apache Apex, Apache Flink, Apache Spark, and Google Cloud Dataflow. |
| </p> |
| <p> |
| Beam is particularly useful for Embarrassingly Parallel data processing tasks, in which the |
| problem can be decomposed into many smaller bundles of data that can be processed independently |
| and in parallel. You can also use Beam for Extract, Transform, and Load (ETL) tasks and pure data |
| integration. These tasks are useful for moving data between different storage media and data |
| sources, transforming data into a more desirable format, or loading data onto a new system. |

| <b>Kata:</b> Your first kata is to create a simple pipeline that takes a hardcoded input element |
| "Hello Beam". |
