Work Description: robertwb opened a new pull request #6986: [BEAM-5999]
Reconcile timer proto representation.
URL: https://github.com/apache/beam/pull/6986
This adds a coder field to the timer spec, and moves the Java executor to
use this spec alone when constructing executable graphs (and Python does). It
should unblock Python timers working on Flink once #6981 also goes in.
