PlanetScale, summarized in your digest

TIN v1.0.6 adds language-specific stemming for 18 languages, supports heap-attribute tiebreakers in ranked top-k queries, and improves top-k performance without changing the index format. Benchmarks on 150 million Stack Exchange documents show TIN outperforming ParadeDB across conjunction, disjunction, phrase, and mixed queries: default scoring delivers 3.1–5.0x higher throughput and 2.7–4.4x lower p99 latency on x86-64. Existing indexes need no rebuild for the performance update; stemming requires rebuilding.

Leaky buckets, first used as ancient water clocks, became a low-cost software pattern for admission control: work is admitted when capacity exists and throttled as the bucket refills over time. Shopify uses query-cost buckets for GraphQL rate limiting. In 2026, PlanetScale brought similar decision gates to Postgres with Database Traffic Control, which estimates query costs, applies tagged resource budgets, and can warn or block queries based on server share, burst capacity, per-query limits, and concurrent workers.
