STRATEGY
Neki is a router speaking the Postgres wire protocol in front of shards that are each a genuine Postgres cluster (1 primary, 2+ replicas across AZs). The discipline is the strategy: no custom storage engine, no hidden shard key, no 'Postgres-compatible' dialect. Routing, pooling (sidecars sized from inside each node, beating PgBouncer), online DDL, version upgrades, and resharding are all workflows driven through the same psql connection the app uses. You can run unsharded on day one and reshard later.
IMPACT
This attacks the ceiling that kills fast-growing Postgres shops - vacuum, index, backup windows, connection limits, transaction wraparound. It legitimizes 'shard later' as an architecture, removing the premature-scaling tax that pushes teams into exotic distributed databases they later regret.
MOATS
The moat is the operational automation: topology-driven planning, online resharding, and zero-downtime upgrades - eight years of running the largest sharded MySQL fleets in the world, re-cast onto Postgres. The wire-protocol compatibility means near-zero switching cost to try it.
