java.lang.Object

com.google.cloud.dataflow.examples.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 general pipeline configuration: --project= and the BigQuery table for the output: --output=:.

To execute this pipeline using the Dataflow service, specify pipeline configuration: --project= --stagingLocation=gs:// --runner=BlockingDataflowPipelineRunner and the BigQuery table for the output: --output=:.

The BigQuery input table defaults to clouddataflow-readonly:samples.weather_stations and can be overridden with --input.
