Bbtree Released: High-Performance Ordered Map for AI Infra
- Replaces skiplists in LSM-trees with 1.37–6.83x faster lookups
- Supports direct Mmap from disk, delivering first responses 160–2500x faster than std's BTreeMap after restart
- Simpler interface without epoch or pinning requirements, easing integration into Rust-based AI backends
