kevy-replicate

Primary-to-replica streaming replication for kevy. Pure Rust, zero crates.io dependencies.

A single primary streams every applied mutation to N read replicas over a long-lived TCP connection, framed in a RESP-extended format that carries a monotonic offset envelope. New replicas first receive an inline snapshot, then catch up live from the frame stream.

Used by both the kevy server (the primary side and the server-as-replica runner) and the embedded library (Store::open_replica).

Audience

Internal infrastructure for the kevy server and the kevy-embedded library. End users configure replication via the server's [replication] TOML section or Store::open_replica / Config::with_replica_upstream on the embedded side. See docs/replication.md.
