DotPulsar.Extensions.Schemas 0.2.0

DotPulsar Schema Extensions

Provides support for using Json and ProtoBuf producers, consumers, and receivers.

It is important to note that this library does not use the official Pulsar Schema Registry. The types provided are merely for convenience on top of the existing Schema.ByteSequence schema.

Installation

dotnet add package DotPulsar.Extensions.Schemas

Usage

A JSON schema can be created using JsonSchema.Get<T>(). This schema can be used to create a producer, consumer, or receiver.

await using var producer = client.NewProducer(JsonSchema.Get<YourType>())
	.Topic("persistent://public/default/my-topic")
	.Create();

Custom serialization options can be passed into the constructor new JsonSchema<T>(options) or by overriding the default options using JsonSchema.DefaultSerializerOptions.

The same can be done for ProtoBuf schemas using ProtoBufSchema.Get<T>(). Currently, only protbuf-net serializable types are supported.

await using var producer = client.NewProducer(ProtoBufSchema.Get<YourType>())
	.Topic("persistent://public/default/my-topic")
	.Create();

Both JsonSchema and ProtoBufSchema support passing a custom ISchema<ReadOnlySequence<byte>> schema. This allows for custom handling of the bytes that are sent and received. One potential use case would be to implement custom encryption or compression of the message bytes.
