Currently, carbon SDK files output (files without metadata folder and its contents) are read by spark using an external table with carbon session. But presto carbon integration doesn't support that. It can currently read only the transactional table output files.
Hence we can enhance presto to read SDK output files. This will increase the use cases for presto-carbon integration. The above scenario can be achieved by inferring schema if metadata folder not exists and setting read committed scope to LatestFilesReadCommittedScope, if non-transctional table output files are present.
