- Summary: PlanetScale reports sustaining 118.5 million queries per second across 512 Neki shards over 1.22 PiB. Per-shard throughput held within 0.8 percent from 5 to 50 shards. The post states the workload was single-shard point selects by primary key, with no writes, no replicas and no failover during the measured window.
- Why it matters: The scaling figure is narrow by the vendor's own statement, so it bounds sharded read fan-out and says nothing about write or failover behavior.
