MaxPerKeyExamples (java 2.62.0 API)

java.lang.Object
- org.apache.beam.examples.cookbook.MaxPerKeyExamples

```
public class MaxPerKeyExamples
extends java.lang.Object
```
An example that reads the public samples of weather data from BigQuery, and finds the maximum temperature ('mean_temp') for each month.
Concepts: The 'Max' statistical combination function, and how to find the max per key group.
Note: Before running this example, you must create a BigQuery dataset to contain your output table.
To execute this pipeline locally, specify the BigQuery table for the output with the form:
```
 --output=YOUR_PROJECT_ID:DATASET_ID.TABLE_ID
 
```
To change the runner, specify:
```
 --runner=YOUR_SELECTED_RUNNER
 
```
See examples/java/README.md for instructions about how to configure different runners.
The BigQuery input table defaults to apache-beam-testing.samples.weather_stations and can be overridden with --input.
