>   Original Estimate: 0h
>  Remaining Estimate: 0h
>
> 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.
