[ARCHIVE] Partial failure in bulk API calls

Archived 2022.11.20. Content moved to error scenarios and responses.

Question

When performing bulk operations, data may be gathered from many internal endpoints, and compiled into a single bulk response. If a single source does not respond or is unavailable how should the Data Holder respond?

For example, in a call to Get Bulk Balances, a single account may not return a balance. 

Answer

The DSB recommendation is to return a 500 Internal Server Error in this situation. If one item in a bulk response fails, then all fail. The DSB recommends against partial responses.

If you see a need for partial responses, please raise a change request.
