LatticeDB vs SQLite: I Ran the Graph Traversal Benchmarks. The Gap Is Real but the Fine Print Matters

Описание и применение

LatticeDB обеспечивает значительно более быстрый глубокий графовый поиск и объединённый поиск по векторам и тексту в одном встроенном файле, в то время как SQLite лучше подходит для табличных данных, многопроцессного доступа и зрелой экосистемы.

Задача

Choosing an embedded database that can efficiently handle graph traversal, vector search, and full-text search for AI agent memory and other graph-heavy workloads.

Результат

LatticeDB delivers dramatically faster deep graph traversal and unified vector/FTS queries in a single embedded file, while SQLite remains superior for tabular workloads, multi‑process access, and ecosystem maturity.

Рабочий процесс

• 1. Build a 100k-node, 500k-edge graph with power-law degree distribution in SQLite using a single adjacency table and indexes.
• 2. Run recursive CTE queries for 1‑hop, 2‑hop, and variable depth (1‑5) traversals from both a random low‑degree node and the max‑degree hub.
• 3. Measure execution times and compare with LatticeDB benchmark results.
• 4. Analyze performance gaps: SQLite’s per‑level overhead and UNION deduplication explode on deep or high‑degree traversals.
• 5. Apply decision framework: choose SQLite for tabular data, multi‑process access, and ecosystem needs; choose LatticeDB for deep graph traversal, combined vector/FTS queries, and agent memory workloads.
• 6. Consider future scaling: use client‑server DBs if multiple writers or networked access are required.
• 7. Leverage LatticeDB’s changefeed for real‑time embedding pipelines if needed.
