| Specifications | |
| ============== | |
| We formalize some DataFusion semantics and behaviors through specification | |
| documents. These specifications are useful to be used as references to help | |
| resolve ambiguities during development or code reviews. | |
| You are also welcome to propose changes to existing specifications or create | |
| new specifications as you see fit. All specifications are stored in the | |
| `docs/source/specification` folder. Here is the list current active | |
