Common pipeline patterns

Pipeline patterns demonstrate common Beam use cases. Pipeline patterns are based on real-world Beam deployments. Each pattern has a description, examples, and a solution or psuedocode.

File processing patterns - Patterns for reading from and writing to files

• Processing files as they arrive
• Accessing filenames

Side input patterns - Patterns for processing supplementary data

• Slowly updating global window side inputs

Pipeline option patterns - Patterns for configuring pipelines

• Retroactively logging runtime parameters

Custom I/O patterns

• Choosing between built-in and custom connectors
