Cheatsheet: Pipeline

Topic Overview

Learn the fundamentals of creating, running, and managing Apache Beam pipelines.

Syntax Snapshot

import apache_beam as beam
from apache_beam.options.pipeline_options import PipelineOptions

# Configure pipeline options
options = PipelineOptions(runner="DirectRunner")

# Define and execute the pipeline
with beam.Pipeline(options=options) as p:
    (p 
     | "Create Data" >> beam.Create(["A", "B", "C"])
     | "Print" >> beam.Map(print))

Key Points

• A Pipeline represents the entire execution graph of transforms.
• The symbol '|' (pipe) is used to apply a transform to a PCollection.
• Using the 'with' context manager automatically triggers pipeline execution at the end of the block.
• Provide descriptive, unique names for every transform stage using the syntax: 'TransformName' >> transform.
