public class JoinExamples
extends Object

This example shows how to do a join on two collections. It uses a sample of the GDELT 'world event' data (http://goo.gl/OB6oin), joining the event 'action' country code against a table that maps country codes to country names.

Concepts: Join operation; multiple input sources.

To execute this pipeline locally, specify a local output file or output prefix on GCS:

   --output=[YOUR_LOCAL_FILE | gs://YOUR_OUTPUT_PREFIX]
 

To change the runner, specify:

   --runner=YOUR_SELECTED_RUNNER
 
 

See examples/java/README.md for instructions about how to configure different runners.
