ASF GitHub Bot commented on BEAM-3388:
--------------------------------------
herohde opened a new pull request #4323: [BEAM-3388] Type-specialize custom
decoders and encoders in Go SDK runtime
URL: https://github.com/apache/beam/pull/4323
Removes the reflective overhead for custom encoders and decoders of certain
types. This is a "poor man's templates" approach.
Once #4289 is in, I'll change the element coding to not reinspect the coder
structure for each element. That will both speed things up and avoid memory
reallocations.

> 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
