Company
PlanetScale is a cloud database platform offering serverless, horizontally-sharded MySQL and Postgres with tools for scaling and schema changes.
Cloudflare moved its main blog from WordPress to EmDash, its own TypeScript CMS, on a Worker stack tested to 7,000 requests per second. The test ran on a cached blog built from Cloudflare services, so the figure carries over only to sites whose pages cache as well.
Reality
The extension puts BM25 ranking behind an ordinary Postgres index, so a newly committed row is searchable without a trip to an Elasticsearch cluster. PlanetScale's own benchmark reports 199 queries per second against ParadeDB's 7.9.
Reality
Neki puts a fleet of connection-owning routers in front of sharded Postgres, each emitting a topology plan you can read with EXPLAIN (NEKI_PLAN). Sessions live on the router holding them, so losing one is visible to the client.
Reality
The 118.5 million read figure came from 512 PostgreSQL primaries answering primary-key lookups, with no replicas attached and 87.3 percent of reads served from cache at peak. Writes, failover and cross-shard work were not in the test.
Reality
Free quotas expire on the vendor's schedule, and on AI platforms that schedule is measured in months. The exit costs more than re-plumbing, so it belongs in the integration budget.
