> Hello !
> This is my first time participating in the open source community as a junior developer and I would like to thank you all for your hard work :)
> While using the new pqarrow package for our project [Metronlab/bow|https://github.com/Metronlab/bow] to read parquet files previously written by Pandas.
> An error is returned by function getOriginSchema if the "ARROW:schema" base64 encoded value is ending with padding characters.
> This is caused by the use of the [RawStdEncoding|https://pkg.go.dev/encoding/base64#pkg-variables] type that omits padding characters.
> Is there any reason for using raw encoding instead of standard?
> Here is a repo with a test script to demonstrate the problem: [antoinegelloz/arrowparquet|https://github.com/antoinegelloz/arrowparquet]
> Thank you in advance for your help,
> Antoine Gelloz
