DKNet.AspCore.Idempotency.NpgsqlStore

NuGet License: MIT

PostgreSQL-backed persistent store for DKNet.AspCore.Idempotency, built on the shared EF Core relational store (DKNet.AspCore.Idempotency.Relational).

✨ Why use it?

  • Persistent – idempotency keys live in a Postgres IdempotencyKeys table, surviving app restarts.
  • Atomic under concurrency – a unique index on the composite key serializes duplicate requests in the database itself; no application-level locking needed.
  • Migrations included – ships with its own EF Core migration and applies it automatically on first use, independently per connection string.
  • Multi-database ready – register the store against several Postgres databases (e.g. per tenant) from the same process; each one is prepared on its own.
  • Npgsql-tuned – retry-on-failure and split-query behaviour are configured out of the box.

🚀 Quick Start

dotnet add package DKNet.AspCore.Idempotency.NpgsqlStore

using DKNet.AspCore.Idempotency;
using DKNet.AspCore.Idempotency.NpgsqlStore;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddIdempotencyWithNpgsqlStore(
    builder.Configuration.GetConnectionString("IdempotencyDb")!,
    options =>
    {
        options.Expiration = TimeSpan.FromHours(48);
        options.ConflictHandling = IdempotentConflictHandling.CachedResult;
    });

var app = builder.Build();

app.MapPost("/orders", CreateOrderAsync)
    .RequiredIdempotentKey();

app.Run();
