This should speed up ParquetReader initialization by skipping a GCS StorageObject lookup that validates that the file exists before trying to open a ReadChannel. Per the doc:
This is redundant, since ParquetRead executes
FileIO.readMatches
before opening any ParquetReaders, which will throw an error on nonexistent files anyway; I tested this with Dataflow and confirmed:Therefore, we know we'll always invoke ParquetReader with an existent file path. Since this metadata lookup can be quite expensive threadpool-wise, so let's skip it since we don't need it.
