118 MILLION QUERIES PER SECOND ON NEKI

Summary from the TLDR Data newsletter

PlanetScale set out to run 1 million queries per second against Neki, its new sharded Postgres, hit that on 5 shards almost immediately, then kept going until 512 shards were serving 118 million queries per second across 1.22 PiB of data. The workload is deliberately narrow: a single-shard point select fetching one row by primary key with no writes, joins, or cross-shard queries, which is what makes the scaling curve clean.
