Module datafusion_planner 

DataFusion-based physical planner for graph queries

Translates graph logical plans into DataFusion logical plans using a two-phase approach:

Phase 1: Analysis

• Assigns unique IDs to relationship instances to avoid column conflicts
• Collects variable-to-label mappings and required datasets

Phase 2: Plan Building

• Nodes -> Table scans, Relationships -> Linking tables, Traversals -> Joins
• Variable-length paths (*1..3) use unrolling: generate fixed-length plans + UNION
• All columns qualified as {variable}__{column} to avoid ambiguity
