Description

https://lists.apache.org/thread.html/cc543556cc709a44ed92262207215eaa0e43a0f573c630b6360d4edc@%3Cdev.beam.apache.org%3E

Implement access to side inputs from arbitrary code via PCollectionView.get().

Not necessarily in scope of this bug: implement inference of which side inputs are needed by detecting fields with a @SideInput annotation.
