Soenneker.Deduplication.SlidingWindow.Registry

A thread-safe registry that creates and reuses one in-memory sliding-window deduplicator per string key.

Installation

dotnet add package Soenneker.Deduplication.SlidingWindow.Registry

Registration

using Soenneker.Deduplication.SlidingWindow.Registry.Registrars;

services.AddSlidingWindowDedupeRegistryAsSingleton();

Singleton registration shares each key’s recent-history window across dependency-injection scopes. Use AddSlidingWindowDedupeRegistryAsScoped() only when each scope should have independent history.

Usage

using Soenneker.Deduplication.SlidingWindow.Abstract;
using Soenneker.Deduplication.SlidingWindow.Registry.Abstract;

public sealed class EventConsumer(ISlidingWindowDedupeRegistry registry)
{
    public async ValueTask<bool> ShouldProcess(string tenantId, string eventId, CancellationToken cancellationToken)
    {
        ISlidingWindowDedupe dedupe = await registry.Get(
            key: $"tenant:{tenantId}",
            window: TimeSpan.FromMinutes(10),
            rotationInterval: TimeSpan.FromSeconds(10),
            cancellationToken);

        return dedupe.TryMarkSeen(eventId);
    }
}

The first successful lookup creates the instance. Later calls for the same key return it even when they supply a different window or rotation interval, so keep those settings consistent.

Releasing inactive keys

Each registry key owns a set and a background rotation timer. The number of registry keys is not bounded; do not derive keys from uncontrolled high-cardinality input.

await registry.Remove($"tenant:{tenantId}", cancellationToken);

// Dispose every cached set and clear all history:
await registry.Clear(cancellationToken);

Removal disposes the cached instance. Do not continue using an instance after its key is removed. A later Get creates a fresh window with the newly supplied configuration. TryGet checks the cache without creating anything.

Dispose the registry itself at the end of its lifetime so all remaining rotation tasks are stopped.
