OrionLock.SqlServer

SQL Server backend for OrionLock using the native sp_getapplock application lock primitive. Session-scope lifetime: the lock is held only while the dedicated SQL session is alive, so a crashed process releases its locks automatically (no clock-based expiry needed).

services.AddOrionLock()
        .UseSqlServer("Server=...;Database=app;Trusted_Connection=true;");

Notes

  • Case-insensitive keys. sp_getapplock @Resource uses the server's default collation; on stock installs "Invoice:42" and "invoice:42" collide. This differs from Redis (case-sensitive). Use KeyPrefix to namespace, not casing.
  • 240-character key limit. Combined KeyPrefix + key must be ≤ 240 characters; longer keys throw ArgumentException. Hash on the caller side.
  • Connection pooling. Leave Microsoft.Data.SqlClient pooling at its default (enabled). The provider holds each session open for the lifetime of the lock and only returns it to the pool after calling sp_releaseapplock, so pool reset is harmless.

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