1//! The complete query processing pipeline.
2//!
3//! Your query goes through several stages before results come back:
4//!
5//! 1. **Translator** - Parses GQL/Cypher/SPARQL into a logical plan
6//! 2. **Binder** - Validates that variables and properties exist
7//! 3. **Optimizer** - Pushes filters down, reorders joins for speed
8//! 4. **Planner** - Converts the logical plan to physical operators
9//! 5. **Executor** - Actually runs the operators and streams results
10//!
11//! Most users don't interact with these directly - just call
12//! [`Session::execute()`](crate::Session::execute). But if you're building
13//! custom query processing, [`QueryProcessor`] is the unified interface.
