Rymote.Synapse.Persistence.Memory

In-memory IMessageLog provider for Rymote.Synapse, enabling the AtLeastOnce dispatch policy without disk persistence.

This provider is ephemeral — process restart loses all un-ack'd entries. For durability across restarts, use Rymote.Synapse.Persistence.File (forthcoming).

What it does

  • InMemoryMessageLog — implements IMessageLog with ack-bounded retention. Entries stay in the log until every active subscription's cursor advances past them.
  • Publisher backpressure: AppendAsync blocks when the log holds MaxLogSize un-ack'd entries; resumes when an ack frees space.
  • MemoryPersistenceOptions.MaxLogSize (default 10 000) caps memory use.
  • UseMemoryPersistence extension on ISynapseBuilder for DI registration.

Quickstart

services.AddSynapse()
    .UseMessagePackSerialization()
    .UseMemoryPersistence(memory => memory.MaxLogSize = 10_000)
    .ConfigureMessageType<PaymentCaptured>(typeOptions =>
        typeOptions.Dispatch = new DispatchPolicy.AtLeastOnce(
            MaxAttempts: 5,
            Backoff: BackoffPolicy.Exponential(TimeSpan.FromSeconds(1), TimeSpan.FromMinutes(1)),
            DeadLetter: new DeadLetterDestination.Channel("payments.dlq")));

ISynapseBus bus = provider.GetRequiredService<ISynapseBus>();

// Subscribers receive the typed message; failures trigger retry-with-backoff;
// after MaxAttempts the message is dead-lettered to "payments.dlq", observable via:
bus.Subscribe<DeadLetterEnvelope<PaymentCaptured>>(async (envelope, context, cancellationToken) =>
{
    // alert / log / forward
});

Limitations

  • Ephemeral — un-ack'd entries are lost on process exit.
  • Strict FIFO per subscription. No in-flight parallelism within one subscription.
  • A subscription that uses FailurePolicy.Rethrow will infinitely redeliver a failing message and pin the log; use Retry → DeadLetter for self-limiting behaviour.
  • A permanently-stuck subscription can block publishers via the MaxLogSize cap. Dispose stuck subscriptions to free the log.
