Excalibur.Dispatch.Serialization.MessagePack

Opt-in MessagePack serialization support for Excalibur framework.

Purpose

Provides high-performance MessagePack binary serialization for:

Ultra-low latency scenarios
Bandwidth-constrained environments
Cross-language interoperability (C++, Python, Rust, etc.)

Usage

Registration (Single Call)

One call does everything -- DI registration, serializer registry entry, and setting MessagePack as the current serializer:

services.AddMessagePackSerializer();

With Custom Options

Pass native MessagePackSerializerOptions for custom configuration:

services.AddMessagePackSerializer(
    MessagePackSerializerOptions.Standard
        .WithCompression(MessagePackCompression.Lz4BlockArray));

Package Dependencies

MessagePack - MessagePack binary serialization runtime
Excalibur.Dispatch.Abstractions - Core contracts only (no Core dependency)

AOT Compatibility

Native AOT compatible with source-generated formatters and resolvers.

Performance Characteristics

Throughput: ~2-5x faster than JSON for binary payloads
Compression: Built-in LZ4 support for bandwidth optimization
Latency: Sub-microsecond serialization for small messages

Architecture Compliance

This package follows the Dispatch serialization policy (R0.14):

Core (Excalibur.Dispatch) - System.Text.Json (default, ADR-295)
Public Edges (Excalibur.Dispatch.Hosting.Web, etc.) - System.Text.Json with source-gen
Opt-In Alternatives (Excalibur.Dispatch.Serialization.*) - Pay-for-play binary serializers

MessagePack is not included in Excalibur.Dispatch to avoid transitive bloat. Consumers must explicitly opt-in by:

Adding <PackageReference Include="Excalibur.Dispatch.Serialization.MessagePack" />
Calling services.AddMessagePackSerializer()

When to Use

Use MessagePack when:

You need maximum throughput and minimum latency
You're sending binary data across services
You need cross-language serialization (non-.NET clients)
You want bandwidth-efficient wire formats

Use System.Text.Json when:

You need human-readable message formats
You're exposing HTTP APIs to external consumers
You require JSON Schema or OpenAPI compatibility

Use MemoryPack when:

You're building internal .NET-to-.NET communication
You need the absolute fastest .NET binary serialization
You control both producer and consumer code

Pluggable Serialization Integration

MessagePack is assigned Serializer ID 3 in the pluggable serialization system. The magic byte 0x03 prefixes all MessagePack-serialized payloads.

Migration Support: When switching from another serializer (e.g., MemoryPack):

Call services.AddMessagePackSerializer() -- old data remains readable via magic byte
New messages use MessagePack
No data migration needed for backward compatibility
