Excalibur.LeaderElection.Postgres

PostgreSQL implementation of leader election for the Excalibur framework. Uses advisory locks (pg_try_advisory_lock) for distributed coordination with automatic failover and session-based locking.

Part Of

This package is included in the following metapackages:

Metapackage	Tier	What It Adds
`Excalibur.Postgres`	Complete	Everything for PostgreSQL: ES + Outbox + Inbox + Saga + LE + Audit + Compliance + Data

Tip: Install Excalibur.Postgres for a production-ready PostgreSQL stack with a single package reference.

Features

Advisory lock-based leader election -- lightweight, session-scoped locks that auto-release on connection loss
Health-based leader election -- extends standard LE with health-aware candidate tracking and voluntary step-down
Factory pattern -- create multiple independent leader elections with different lock keys
Telemetry integration -- OpenTelemetry metrics and traces via TelemetryLeaderElection decorator
Health checks -- ASP.NET Core health check integration

Quick Start

services.AddPostgresLeaderElection(options =>
{
    options.ConnectionString = "Host=localhost;Database=myapp;";
    options.LockKey = 12345;
});

Or using the builder pattern:

services.AddExcalibur(x => x.AddLeaderElection(builder =>
{
    builder.UsePostgres(options =>
    {
        options.ConnectionString = connectionString;
    });
}));
