-----------------------------------------
Summary: Refactor SelectStatement
Key: CASSANDRA-7981
URL: https://issues.apache.org/jira/browse/CASSANDRA-7981
Project: Cassandra
Issue Type: Bug
Reporter: Benjamin Lerer
Assignee: Benjamin Lerer
Fix For: 3.0
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:
* 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.
