> 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 (decimal?). Decimal literal support is already provided in CQL.
> This is low hanging fruit.
