Excalibur.Dispatch.Transport.Pulsar

Apache Pulsar transport for the Excalibur framework, built on the DotPulsar client.

Provides competing-consumer message streaming with a subscription model that mirrors the framework's consumer-group transport semantics.

CloudEvents

Inbound CloudEvents are decoded automatically. Every receiver on this transport is wrapped by the framework's decoding decorator, so a message carrying CloudEvents markers arrives with the decoded event attached to it — the body and properties are untouched, and a message that is not a CloudEvent passes through unchanged. Every message in the batch is delivered, including a malformed one: it arrives carrying a decode error instead of a decoded event, never dropped. There is nothing to register and no option to set.

Outbound CloudEvents are opt-in per message. Attach the event to the message you were going to send anyway:

await sender.SendAsync(message.WithCloudEvent(cloudEvent), cancellationToken);

The event is published in CloudEvents structured mode — the whole event becomes a JSON document in the body under the application/cloudevents+json content type. A message you do not call WithCloudEvent on reaches the wire byte-identical, so ordinary traffic is unaffected, and nothing produces a CloudEvent for you. This path needs no trimming or ahead-of-time annotation: the envelope is written with a UTF-8 JSON writer rather than a reflection-based serializer.

Usage

services.AddPulsarTransport("events", pulsar =>
{
    pulsar.ServiceUrl("pulsar://localhost:6650")
          .Topic("orders")
          .SubscriptionName("order-processors")
          .SubscriptionType(PulsarSubscriptionType.Shared);
});

Subscription types

SubscriptionName is the durable consumer identity (the Pulsar analog of a Kafka consumer group). SubscriptionType controls how messages are distributed across consumers sharing that subscription:

Type Behavior
Shared Competing consumers, round-robin delivery (default).
Exclusive A single consumer holds the subscription.
Failover One active consumer; others stand by.
KeyShared Same-key messages go to the same consumer, preserving key ordering.

Scope

This package registers the Pulsar transport primitives — a keyed ITransportSender and ITransportReceiver for sending, receiving, and acknowledging messages directly against a Pulsar broker. High-level integration into the dispatch pipeline (publishing and consuming typed dispatch messages end-to-end through a transport adapter) is provided separately.

Capabilities

Request/reply is not natively supported. Validation fails fast at startup on invalid configuration.
