             Summary: Reimplement SQL binary type with more efficient data 
structure
                 Key: SPARK-5553
                 URL: https://issues.apache.org/jira/browse/SPARK-5553
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.2.0
            Reporter: Cheng Lian


Spark 1.2.0 and prior versions use {{Array\[Byte\]}} to represent binary type 
values. This is suboptimal. Better candidates can be Java NIO {{ByteBuffer}} 
and Guava {{UnsignedBytes}}.
