-----------------------------------
Summary: Quadratic behavior in go pipeline rewriting.
Key: BEAM-14128
URL: https://issues.apache.org/jira/browse/BEAM-14128
Project: Beam
Issue Type: Bug
Components: sdk-go
Affects Versions: 2.37.0
Reporter: Robert Burke
Work is repeated for every node outside of a given composite, when checking if
anything is using any outputs of transforms internal to the composite.
This bug significantly increases the construction time large pipeline graphs,
but can be resolved with bit of pre-computation and plumbing of which
transforms are using which PCollections.
