ReptiDex's Postgres Pedigree Trees: Scaling Lineage for 200 Animals in Days
A reptile breeder stares at his phone, tracing four generations of bearded dragons back to imported stock. That's the power of ReptiDex's Postgres-backed pedigree trees, live with 50 paying users.
⚡ Key Takeaways
- Adjacency lists with recursive CTEs crush multi-gen pedigree queries in Postgres—fast, integral, scalable to production.
- Nullable self-refs handle real-world incomplete data without breaking trees.
- Denormalize for cache in read-heavy apps; skip closure tables unless writes dominate.
