Upgrade transforms without upgrading the pipeline

Beam Transform Service service allows Beam pipeline authors to upgrade specific transforms within their pipelines to a newer Beam version without upgrading the full pipeline. Please see the Beam programming guide for more details regarding this feature and supported SDKs and Beam versions.

...

• Setup the environment according to the Beam Java quickstart guide.
• Install Docker if not already available in the system.
• Checkout the Beam examples Maven archetype for the relevant Beam version.
  
  

export BEAM_VERSION=<Beam version> # Needs to be Beam 2.53.0 or later.

mvn archetype:generate \
    -DarchetypeGroupId=org.apache.beam \
    -DarchetypeArtifactId=beam-sdks-java-maven-archetypes-examples \
    -DarchetypeVersion=$BEAM_VERSION \
    -DgroupId=org.example \
    -DartifactId=beam-transform-upgrade \
    -Dversion="0.1" \
    -Dpackage=org.apache.beam.examples \
    -DinteractiveMode=false

cd beam-transform-upgrade

• Add the Beam examples Java dependency to the <dependencies> section of the Maven pom.xml file.
  
  

  Code Block
  <dependency> <groupId>org.apache.beam</groupId> <artifactId>beam-examples-java</artifactId> <version>${beam.version}</version> </dependency>

  
  

• Execute the pipeline using a portable Beam runner. Following example uses Dataflow Runner v2.
  
  

export GCP_PROJECT=<GCP project>
export GCP_BUCKET=<GCP bucket>
export GCP_REGION=<GCP region>
export OUTPUT_BIGQUERY_TABLE=<A BigQuery table to write the output to>
export TRANSFORM_BEAM_VERSION=<Beam version to upgrade transforms to> # Needs to be Beam 2.53.0 or later.

mvn compile exec:java -Dexec.mainClass=org.apache.beam.examples.cookbook.BigQueryTornadoes -Dexec.args="--runner=DataflowRunner --project=$GCP_PROJECT \
                 --region=$GCP_REGION \
                 --tempLocation=gs://$GCP_BUCKET/transform-upgrade/tmp \
                 --experiments=use_runner_v2 --output=$OUTPUT_BIGQUERY_TABLE \
                 --transformsToOverride=beam:transform:org.apache.beam:bigquery_read:v1,beam:transform:org.apache.beam:bigquery_write:v1 \
                 --transformServiceBeamVersion=$TRANSFORM_BEAM_VERSION" -Pdataflow-runner
