Hey @HarshCasper! Is it possible to add the known limitations to this page? The basic functionality of ServiceBus (sending/receiving messages) is fully implemented, but there are some missing features that may be worth pointing out.

These are all the limitations that we know about:

• AMQP-over-websocket is not supported, only AMQP
• Transactions are not supported
• Auto-forwarding of messages (chaining of queues) is not supported
• There is no validation of limitations like max number of entities, max message size
• Renewing message locks is not supported
• The message count in the Queue properties may not be accurate

Hi @bblommers it looks we worked on the same article at the same time. Great minds think alike as you said in Slack 😅

@HarshCasper Please find below the sections to add at the end of the article before the API Coverage section. I integrated Bert's bullet points.

Features

The emulator includes the following core capabilities:

• Data Plane REST API: Supports message-level operations, including Send, Receive, and Peek.
• Control Plane REST API: Enables CRUD operations for namespaces and messaging entities (queues, topics, and subscriptions) via Azure Resource Manager (ARM).
• Multiple Authentication Modes: Supports both Connection String and Managed Identity authentication.
• Containerized Deployment: Runs as a lightweight, Linux-based Docker container.
• Cross-Platform Compatibility: Fully compatible with Windows, macOS, and Linux environments.
• Flexible Configuration: Manage Service Bus entities via the Service Bus Administration Client or through JSON-based configuration files.
• Advanced Streaming: Supports message streaming via the Advanced Message Queuing Protocol (AMQP).

Limitations

The current version of the emulator does not support the following:

• Protocols: JMS protocol streaming and AMQP Web Sockets (AMQP over TCP is the only supported transport).
• Messaging Patterns: Transactions, auto-forwarding (queue chaining), and message lock renewal.
• Validation: Enforcements such as maximum entity counts or maximum message sizes.
• Metrics: Property-based message counts for queues, topics, and subscriptions may be inaccurate.

The following Azure-native features are currently unavailable in the emulator:

• Scaling & Resiliency: Autoscale, Geo-disaster recovery, and Large Message support.
• Monitoring: Visual metrics, alerts, and telemetry dashboards.

Samples

Thanks @HarshCasper, the article looks amazing. I like how you used curl to invoke the data plane API. Please integrate the additional sections from my comment below. Reach out to me and @bblommers once those are addressed, and we’ll get this approved right away.
