1//! Query processing pipeline.
2//!
3//! This module provides the complete query execution pipeline:
4//!
5//! - **Translators**: Convert query languages (GQL, Cypher, SPARQL, etc.) to logical plans
6//! - **Binder**: Semantic validation and variable resolution
7//! - **Optimizer**: Plan optimization (filter pushdown, join reorder, etc.)
8//! - **Planner**: Convert logical plans to physical operators
9//! - **Executor**: Execute physical operators and collect results
10//! - **Processor**: Unified interface orchestrating the full pipeline
11//! - **Cache**: LRU cache for parsed and optimized query plans
