[jira] [Created] (BEAM-3388) Reduce Go runtime reflective overhead

Henning Rohde created BEAM-3388:
-----------------------------------

             Summary: Reduce Go runtime reflective overhead
                 Key: BEAM-3388
                 URL: https://issues.apache.org/jira/browse/BEAM-3388
             Project: Beam
          Issue Type: Improvement
          Components: sdk-go
            Reporter: Henning Rohde
            Assignee: Henning Rohde


Go reflection is slow and we should avoid it in the Go SDK at runtime, when possible -- especially on the fast paths. It seems unlikely that the language runtime/libraries will improve any time soon: https://github.com/golang/go/issues/7818.
