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.AddExcaliburLeaderElection(builder =>
{
    builder.UsePostgres(options =>
    {
        options.ConnectionString = connectionString;
    });
});
