                 Key: CASSANDRA-1705
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1705
             Project: Cassandra
          Issue Type: Sub-task
          Components: API
    Affects Versions: 0.8
            Reporter: Eric Evans
            Priority: Minor
             Fix For: 0.8


CQL specification and implementation for data manipulation.

This corresponds to the following RPC methods:

* insert()
* batch_mutate() (writes, not deletes)

The initial check-in to trunk/ uses a syntax that looks like:

{code:SQL}
UPDATE <CF> [USING CONSISTENCY.<LVL>] WITH ROW(<key>, COLUMN(<name>, <value>)[, 
COLUMN(...)])[ AND ROW(...)];
{code}

Where:
* <CF> is the column family name.
* Rows are a parenthesized expressions with comma separated arguments for a key 
and one or more columns.
* Columns are a parenthesized expressions with comma separated arguments for 
the name and value (timestamp is inaccessible).

What is still undone:
* Complete test coverage

And of course, all of this is still very much open to further discussion.
