Mediarq.Idempotency

Run a request at most once per key. A repeated request that implements IIdempotentRequest with the same key replays the stored result instead of re-executing the handler — so a retried POST won't double its effect.

dotnet add package Mediarq.Idempotency

Usage

builder.Services.AddDistributedMemoryCache();   // REQUIRED: an IDistributedCache (use Redis in production)
builder.Services.AddMediarqIdempotency();

public record ConfirmOrder(Guid OrderId, string IdempotencyKey) : ICommand<Result>, IIdempotentRequest
{
    public TimeSpan? IdempotencyDuration => TimeSpan.FromMinutes(10);
}

// e.g. read the key from an Idempotency-Key header
var key = http.Headers["Idempotency-Key"].FirstOrDefault() ?? Guid.NewGuid().ToString();
await sender.Send(new ConfirmOrder(id, key));

Call after AddMediarq / AddMediarqCore. Use a stable, caller-supplied key. The stored result is JSON-serialized; Result / Result<T> round-trip out of the box. For strict once-only semantics under high concurrency, back it with a store that supports atomic set-if-absent (e.g. Redis).

Persistent stores

IdempotencyBehavior depends on the standard IDistributedCache — swap the backing store without any code change:

  • In-memory (single process, non-persistent): AddDistributedMemoryCache() — shown above.
  • Redis: AddStackExchangeRedisCache(o => o.Configuration = "...").
  • Your own SQL database: Mediarq.Idempotency.EntityFrameworkCore — AddMediarqIdempotencyEntityFrameworkCore<TContext>(), no Redis required.
