I think we can enhance the existing APIs itself to take folder path and
then list from the first available data file or index file.. Adding many APIs
in SDK will cause confusion for same functionality. I think we can unify to
single method like getSchemaFromPath() and return the schema irrespective of
index file or data file or multiple subfolders.---
