This module contains a series of Beam YAML code samples that can be run using
the command:
```
python -m apache_beam.yaml.main --pipeline_spec_file=/path/to/example.yaml
```

## Wordcount
A good starting place is the [Wordcount](wordcount_minimal.yaml) example under
the root example directory.
This example reads in a text file, splits the text on each word, groups by each
word, and counts the occurrence of each word. This is a classic example used in
the other SDK's and shows off many of the functionalities of Beam YAML.

## Transforms

Examples in this directory show off the various built-in transforms of the Beam
YAML framework.

### Element-wise
These examples leverage the built-in mapping transforms including `MapToFields`,
`Filter` and `Explode`. More information can be found about mapping transforms
[here](https://beam.apache.org/documentation/sdks/yaml-udf/).

### Aggregation
These examples leverage the built-in `Combine` transform for performing simple
aggregations including sum, mean, count, etc.

More information can be found about aggregation transforms
[here](https://beam.apache.org/documentation/sdks/yaml-combine/).
