OrionLock.Postgres

PostgreSQL pg_try_advisory_lock backend for OrionLock distributed locking.

Lock lifetime is the PostgreSQL session lifetime: a crashed process releases its locks automatically with no clock-based expiry.

services.AddOrionLock()
        .UsePostgres("Host=localhost;Database=app;Username=...;Password=...", o =>
        {
            o.KeyPrefix = "app:";
            o.CommandTimeout = TimeSpan.FromSeconds(30);
        });

Notes

  • 64-bit integer keys. Postgres advisory locks are keyed by bigint. The provider hashes KeyPrefix + key with SHA-256 and takes the first 8 bytes as a little-endian int64. Collision risk is negligible for realistic key counts; use KeyPrefix to namespace if you also share the database with pg_advisory_lock from other code paths.
  • Session-scoped, no clock expiry. A crashed process releases its locks the moment the database session terminates. There is no lease timer in Postgres itself; OrionLock's renewal watchdog only probes the connection liveness.
  • Connection pooling. The provider holds each dedicated NpgsqlConnection open for the lifetime of the lock and disposes it on release, returning it to the Npgsql pool only after pg_advisory_unlock has run.

Requires the OrionLock package. See https://github.com/tunahanaliozturk/OrionLock.
