Goal We want to retrieve user profile data for thousands of users in a single operation. The operation must finish in under 1 second when the service receives 200 concurrent requests. Context Under heavy load, the average round‑trip time for a single Graph API call spikes to 300 ms, causing the overall pipeline to exceed the SLA. Two documented approaches ex
When retrieving large collections through the Facebook Graph API, developers often increase the limit parameter to reduce the number of round‑trips. However, raising the limit can also increase server‑side processing and network transfer time, potentially creating a bottleneck before any optimization is applied. The exact point where latency begins to grow d
Migration goal I am planning to migrate a small application to a new Azure AD B2C User Flow without downtime. The documented approach of on-the-fly user import via the Microsoft Graph API, combined with a staged cutover using a new User Flow and gradual traffic redirection, looks workable in principle. Open concerns Two behaviors remain unclear to me before
Dataset Retrieval and Pagination When retrieving large datasets from Azure DevOps, the REST API typically employs server-side pagination. For many endpoints, this is managed via the x-ms-continuationtoken header, which allows clients to request subsequent pages by passing a continuationToken parameter.
