I store a full 32 bit integer encoding for the scale part of the data into C*,
which is what the Java class {{BigDecimal}} supports. but for a scale factor
that is crazy huge. I could easily be talked into using just a byte to support
128 or 256 scale. that is still 256 digits after the decimal... The unscaled
value is stored like {{IntegerType}}.

Key: CASSANDRA-2883
URL: https://issues.apache.org/jira/browse/CASSANDRA-2883
Project: Cassandra
Issue Type: Sub-task
Components: Core
Affects Versions: 0.8.1
Reporter: Rick Shaw
Assignee: Rick Shaw
Priority: Trivial
Labels: CQL, JDBC,, lhf
Fix For: 0.8.6
Attachments: add-decimaltype-v1.txt
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.

Don't we need to add antlr support for specifying the type as
decimal(precision, scale)?

On second thought, just allowing any decimal is fine to start with.
