Luke Cwik created BEAM-2771:
-------------------------------
Summary: Allow using side inputs as ValueProviders
Key: BEAM-2771
URL: https://issues.apache.org/jira/browse/BEAM-2771
Project: Beam
Issue Type: New Feature
Components: sdk-java-core, sdk-py
Reporter: Luke Cwik
Priority: Minor
Allow dynamically computed information in a pipeline which is materialized as a
side input to be used in the same places as ValueProviders.
This could solve the problem mentioned in
[https://stackoverflow.com/questions/45649244/google-cloud-dataflow-apache-beam-can-i-use-sideinputs-with-textio-write]
if TextSink supported ValueProviders for headers/footers.
