[jira] [Created] (CASSANDRA-2884) CQL processing engine should
provide server side data binding to pre-compiled CQL scripts
CQL processing engine should provide server side data binding to pre-compiled CQL scripts
-----------------------------------------------------------------------------------------
Key: CASSANDRA-2884
URL: https://issues.apache.org/jira/browse/CASSANDRA-2884
Project: Cassandra
Issue Type: New Feature
Components: API
Affects Versions: 0.8.1
Reporter: Rick Shaw
Fix For: 1.0
The notion of "Prepared" statements is derived from JDBC lore, but is equally useful for the other supported clients of CQL. In order to support server-side binding and pre-compiled code referenceable from the client side, the API (currently Thrift based) will need to be enhanced to pass both script (CQL) and the binding arguments to the server. In addition the parser will need to recognize the place holders for the bound variables ("?"). And the product of the parse will need to be savable and a reference or handle will need to be returned to the client side caller. The execution of C* API calls will need to be moved from the parsers action routines where it is currently executed as the script is parsed, and moved to another "execution" engine that calls API methods and uses the bound variables and the stored pre-compiled code to drive the process.

--------------------------------------
Yes. Seems like it to me as well.
