> {{FileSourceStrategy}} assumes that all data source formats are splittable and always splits data files by fixed partition size. However, not all HDSF based formats are splittable. We need a flag to indicate that and ensure that non-splittable files won't be split into multiple Spark partitions.
> (PS: Is it "splitable" or "splittable"? Probably the latter one? Hadoop uses the former one though...)
