alkstore-postgres
The Postgres engine of the alkstore
family: the core contract implemented on tokio-postgres +
deadpool-postgres, natively async (no blocking bridge, no
spawn_blocking seam), with a hand-rolled LISTEN forwarder.
let store = alkstore_postgres::open(&dsn, alkstore_postgres::PgOpts::default()).await?;
Engine posture — multi-host native. Connections are per-process
state; nothing assumes a shared host. Connection budget: max_size
pooled connections + 1 non-pooled listener connection per LISTEN-ing
process (pooled connections cannot carry LISTEN) — size the server
for the sum. v1 TLS is effectively unavailable: the engine hardwires
NoTls on every connection path, so network confidentiality must come
from the deployment topology. Queue/stream/lock/schedule tables live
in one engine-owned PostgreSQL schema (default alkstore,
per-engine option).
See the family README for the interface and the deployment matrix, and the Postgres engine spec for the driver's details.
