REST & Atomic increment

Hi,

Is there - or are there plans for implementing - an atomic increment method for a column value in the REST API? I noticed such a method in Thrift. 

Just thinking of a way to increment a column value integer in a single operation - avoiding the need for a GET request followed by a PUT request.

Thanks

Mark

Not a preference, per se.

I just imagine calling something like:

	POST increment/<table>/<row>/<column>( : <qualifier> )?( / <timestamp> )?/<increment integer>

Which, if successful returns:

	HTTP/1.1 200 OK
	Content-Type: application/json
	{"$":<new integer>}

I imagine it returning errors in the event of the increment request being applied to a column value that cannot be incremented.

I basically imagine it working in a similar fashion to the HBase shell and Thrift API.

Do you have any preference for how this might be accomplished?
