-------------------------------------------
Go ahead, thank you!
> Rename ToStringCoder into ToBytesCoder
> --------------------------------------
>
> Key: BEAM-7198
> URL: https://issues.apache.org/jira/browse/BEAM-7198
> Project: Beam
> Issue Type: Sub-task
> Components: sdk-py-core
> Reporter: Valentyn Tymofieiev
> Priority: Minor
>
> The name of ToStringCoder class [1] is confusing, since the output of
> encode() on Python3 will be bytes. On Python 2 the output is also bytes,
> since bytes and string a synonyms on Py2.
> ToBytesCoder would be a better name for this class.
> Note that this class is not listed in coders that constitute Public APIs [2],
> so we can treat this as internal change. As a courtesy to users who happened
> to reference a non-public coder in their pipelines we can keep the old class
> name as an alias, e.g. ToStringCoder = ToBytesCoder to avoid friction, but
> clean up Beam codeabase to use the new name.
