   Thanks @thinkharderdev for proposing these potentials.

   For this, actually our team has implemented for the HDFS. To avoid new object store registration, our workaround is to make the path self description with its scheme, like hdfs:://localhost:15050/..../file.parquet. Then with the scheme, we will know which kind of remote object store we needs.

   Maybe it's better to introduce the substrait integration into the roadmap.
