+Apache CarbonData(incubating) is a new big data file format for faster
interactive query using advanced columnar storage, index, compression
and encoding techniques to improve computing efficiency, in turn it will
help speedup queries an order of magnitude faster over PetaBytes of data.

### Features
CarbonData file format is a columnar store in HDFS, it has many features that a modern columnar format has, such as splittable, compression schema ,complex data type etc, and CarbonData has following unique features:
* Stores data along with index: it can significantly accelerate query performance and reduces the I/O scans and CPU resources, where there are filters in the query. CarbonData index consists of multiple level of indices, a processing framework can leverage this index to reduce the task it needs to schedule and process, and it can also do skip scan in more finer grain unit (called blocklet) in task side scanning instead of scanning the whole file.

* Column group: Allow multiple columns to form a column group that would be stored as row format. This reduces the row reconstruction cost at query time.
* Supports for various use cases with one single Data format : like interactive OLAP-style query, Sequential Access (big scan), Random Access (narrow scan).
