Hi everyone, I am working on a project that enables the splittable reading for ParquetIO.The JIRA issue is here <https://issues.apache.org/jira/browse/BEAM-4379> and I have created a PR <https://github.com/apache/beam/pull/12223> for the issue. I have also attached my design doc <https://docs.google.com/document/d/1xqN7qsV3vsrqd6i18isAA1HTWmTMXK-u4sle-brXxuw/edit?usp=sharing> for the function and can you please provide some feedback/suggestions?
Thanks Jiadai Xia
