The multi-level indexing feature in Carbondata seems very interesting...it will allow persisting OLAP cubes and provide efficient access; virtually providing the capability that specialized OLAP engines provide. The ORC format also provides indexing but it seems not multi-level indexing.
Another promising use is for secondary indexing. Basically, making the file format competitive with NoSQL systems that support secondary indexes.
