Benjamin Lerer updated CASSANDRA-7981:
--------------------------------------
Component/s: CQL
> Refactor SelectStatement
> ------------------------
>
> Key: CASSANDRA-7981
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7981
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Benjamin Lerer
> Assignee: Benjamin Lerer
> Fix For: 2.2.0 beta 1
>
>
> The current state of the code of SelectStatement make fixing some issues or
> adding new functionnalities really hard. It also contains some
> functionnalities that we would like to reuse in ModificationStatement but
> cannot for the moment.
> Ideally I would like to:
> * Perform as much validation as possible on Relations instead of performing
> it on Restrictions as it will help for problem like the one of
> #CASSANDRA-6075 (I believe that by clearly separating validation and
> Restrictions building we will also make the code a lot clearer)
> * Provide a way to easily merge restrictions on the same columns as needed
> for #CASSANDRA-7016
> * Have a preparation logic (validation + pre-processing) that we can easily
> reuse for Delete statement #CASSANDRA-6237
> * Make the code much easier to read and safer to modify.
