------------------------------------
Summary: Get runners out of the apply()
Key: BEAM-646
URL: https://issues.apache.org/jira/browse/BEAM-646
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Kenneth Knowles
Assignee: Thomas Groh
Right now, the runner intercepts calls to apply() and replaces transforms as we
go. This means that there is no "original" user graph. For portability and misc
architectural benefits, we would like to build the original graph first, and
have the runner override later.
Some runners already work in this manner, but we could integrate it more
smoothly, with more validation, via some handy APIs on e.g. the Pipeline object.
