Add Support for BigDecimal Java data type as the "NumericType" AbstractType
---------------------------------------------------------------------------

                 Key: CASSANDRA-2883
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2883
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
    Affects Versions: 0.8.1
            Reporter: Rick Shaw
            Priority: Trivial
             Fix For: 0.8.2


The JDBC Driver suite needs support for {{BigDecimal}} to complete it's data type support
for {{ResultSet}} and {{PreparedStatement}}. This datatype could also be used to represent
numeric (non-integer) counter values. This is a very simple addition to the collection of
data types supported by Cassandra. It is quite versatile like {{BigInteger}}. It can represent
decimal numbers of virtually any precision and scale. It is represented in Java as an arbitrary
precision integer unscaled value ( think {{IntegerType}} )and a 32-bit integer scale factor,
which could be represented as a {{IntegerType}} as well. This could share much of the logic
from the {{BigInteger}} ({{IntegerType}}) implementation. 

CQL would need to add a datatype (numeric?). Decimal literal support is already provided in
CQL.

This is low hanging fruit.
