Question 1

What is pg-kinetic?

Accepted Answer

pg-kinetic is an open-source, drop-in Rust PostgreSQL wire proxy that keeps PostgreSQL responsive during connection spikes with transaction pooling, route-level backpressure, routing, and operator-visible health.

Question 2

How does pg-kinetic handle overload?

Accepted Answer

It applies queues and deadlines per route. When a route is full, pg-kinetic returns a PostgreSQL 53300 overload error quickly, keeping the capacity assigned to other routes available.

Question 3

Does pg-kinetic require application driver changes?

Accepted Answer

Applications continue to speak the PostgreSQL protocol. Start with a connection-string change, keep the original PostgreSQL path available during a canary, and verify driver and session-state behavior for the workload.

Question 4

Where is the pg-kinetic documentation?

Accepted Answer

The documentation covers configuration, migration, routing, sharding, policy, observability, testing, and benchmarks.
