 ### 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. 
 * Operable encoded data :Through supporting efficient compression and global encoding schemes,
can query on compressed/encoded data, the data can be converted just before returning the
results to the users, which is "late materialized". 
-* 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).
