| |
| <p>Consider this package to be the "standard library" of planner rules. |
| Most of the common rewrites that you would want to perform on logical |
| relational expressions, or generically on any data source, are present, |
| and have been well tested. |
| |
| <p>Of course, the library is never complete, and contributions are welcome. |
| |
| <p>Not present are rules specific to a particular data source: look in that |
| data source's adapter. |
| |
| <p>Also out of the scope of this package are rules that support a particular |
| operation, such as decorrelation or recognizing materialized views. Those are |
| defined along with the algorithm. |
