Built by Rebus FM

When building Copper Power Platform, the requirement for an M7 integration that was clean, usable, and confidence-inspiring led to the creation of Copper M7.

Because of its reliance on RabbitMQ/AMQP 0.9.1, a fairly involved messaging protocol, and the requirement of being able to gracefully handle failover, integrating with EPEX M7 is notoriously difficult.

Copper M7 hides all the messy details, making it possible for developers to focus on developing their own stuff. 🙂

It comes in the form of a NuGet package and is built with state-of-the art .NET 7, integrating seamlessly into Microsoft's generic host.

Hosting

Tapping into Microsoft's generic host model, starting your robust M7-powered integration service is just as easy as calling an extension method on your IServiceCollection.

Initial sync

Doing the initial sync is done simply by providing a callback. Copper M7 will call it during startup, and subsequently whenever it is required.

...
...

Broadcasts

Broadcast messages get dispatched to the broadcast dispatcher function.

Copper M7 guarantees that you'll receive broacast messages in the correct order.

Message models

All message types are represented as C# classes. In addition to this, types are marked with interfaces, classifying messages as one or more of IInquiryRequest, IInquiryResponse, IManagementRequest, IManagementResponse, IBroadcastMessage, AND finally all requests are marked with their return types, e.g. TradeCaptureReq is marked with IReturn<TradeCaptureRprt>

...
...

High-level helpers

Copper M7 automatically retrieves and caches relevant entities, keeping them updated in the background.

They can be accessed via dedicated helpers, e.g. IContractHelper, which may be used to easily get contract information.

Dependency injection

Handlers for initial sync and broadcast message processing can be registered with services.AddInitialSyncHandler<> and services.AddBroadcastHandler<>, e.g. services.AddBroadcastHandler<TradeCaptureRprtHandler>(); for full dependency injection support.

  • For example:

  • Higher-level helpers: The ability to register handlers that will automatically be kept up-to-date with regards to interesting exchange entities, e.g. like products, orders, trades, etc.
  • Decoders: Helpers for decoding prices and quantities with correct observation of their respective value metadata
  • Caching: Automatic, in-process caching of relevant, less-often changes registry data, like e.g. available areas, products, contracts, account information, etc.
  • Request limiting: Request rates are automatically and without effort confined to stay within required limits, thus avoiding being penalized for flooding M7.
  • Heartbeat monitoring: An internal watchdog automatically monitors for M7 heartbearts, restarting the connection if the M7 server suddenly becomes quiet.
