Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
SQLite and file-based storage can become bottlenecks under heavy load, leading to contention and performance degradation.
Designed primarily for single-machine use; lacks native support for multi-node clustering or distributed environments.
Official documentation focuses on basic operations, leaving users to figure out more complex scenarios without guidance.
Fit analysis
Who is it for?
✓ Best for
