>
> The WindowedValueHolder is a Python type that requires a special
> `SafeFastPrimitivesCoder` instead of the native `FastPrimitivesCoder` in
> cache_manager to encode and decode.
> When reading cache of it and applying an external transform such as a
> SqlTransform, it introduces a pickled Python coder that is not xLang friendly.
> We could build a Row schema to hold the WindowedValueHolder to make the cache
> reading xLang friendly and also get rid of the additional layer of
> `SafeFastPrimitivesCoder`.
