Heejong Lee created BEAM-7220:
---------------------------------
Summary: add JavaReadViaImpulse substitution to Java expansion
service
Key: BEAM-7220
URL: https://issues.apache.org/jira/browse/BEAM-7220
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Heejong Lee
Read transform is not supported in the portability framework. `PortableRunner`
substitutes Read transform with Impulse + DoFn before it submits a pipeline to
JobServer. However, when ExternalTransform is used, this substitution logic
doesn't work. Looks like it should be doneĀ in the expansion service instead
until we completely remove JavaReadViaImpulse hack.
