------------------------------------------

             Summary: Adding Data Types and Structured Row Keys in 0.89-fb HBase
                 Key: HBASE-10756
                 URL: https://issues.apache.org/jira/browse/HBASE-10756
             Project: HBase
          Issue Type: New Feature
          Components: Usability
    Affects Versions: 0.89-fb
            Reporter: Manukranth Kolloju
            Assignee: Manukranth Kolloju
             Fix For: 0.89-fb


As an extension to some of the work done on Presto + HBase side, and also inspired by some
of the work done on open source and Pheonix, introducing data types and structured row keys
will enable the data base(hbase) to de-couple database level optimizations from the application
level schema. The attempt is to provide a table definition & specification to define the
row key structure which can be composed as a composite struct composed of primitive data types.
The data base can make intelligent decisions of how to interpret the data. For instance, having
an understanding of the the structure of row key will hint the database about the parts of
the data that are valuable and can use that information to construct indexes/bloom filters
based on these parts of the row key.

This can be extended to the column qualifiers and Nested Types as well.
