Hi,

It is known that if we need to use business events, the payload needs to be light in weight. May i ask what is the definition of light weight? So if we return 100 fields, is this considered heavy? Or what is the max acceptable number of fields we should return? And what would be the effect if we return alot?

I have the same question (0)

Business events payload

Hi,

The concept of a "lightweight" payload for business events generally refers to sending only the essential data needed for the specific business process. The goal is to minimize the amount of data transferred in order to improve performance, reduce latency, and avoid overwhelming the system or the downstream components that consume the event.

Returning 100 fields in a business event payload is considered relatively heavy, especially if many of those fields are not directly relevant to the specific event. There isn't a strict, fixed number of fields that defines "lightweight" or "heavy" as it can vary based on your specific use case and the performance characteristics of your Dynamics 365 environment. However, it's a best practice to keep payloads as minimal as possible.

The effect of returning a lot of data in business event payloads can include:

Performance Impact: Heavier payloads can slow down the processing of events, impacting system performance and responsiveness.

Increased Latency: Large payloads take longer to transmit and process, potentially increasing the time it takes for the event to be processed.

Resource Consumption: The system's resources, such as memory and CPU, may be more heavily utilized when dealing with large payloads.

To keep payloads lightweight, you should only include the data necessary for the specific event and its consumers. If you find that you need to send a large amount of data, consider whether it's possible to break the data into smaller, more targeted events or use other integration methods to transfer bulk data.

Best regards,

Kevin
