Background

EdgeIndex uses narrow rows, requiring N scan API calls for the 2nd hop in multi-hop queries. A wide row structure is introduced to enable multi-get and resolve this. A process to prevent fat rows is also introduced alongside.

Extending from independent per-feature edge queries to cross-feature graph traversal (Unified Graph).

Task

• Phase 0: Design alignment with core model via skeleton E2E
  [0/4] Multi-hop query: skeleton E2E #217
• Phase 1: Mutation + multi-get query to verify (not n-hop yet)
  [1/4] Multi-hop query: Mutation + multi-get query #226
• Phase 2: Query - 2-hop or more
• Phase 3: Server with E2E from Phase 0
• Phase 4: Pruner (fat row prevention)

Done When

• Design alignment based on skeleton
• 2-hop query works in 1+1 API calls
• E2E tests pass

Notes

• Implement n-hop generalization
