Only the requests exceeding the limits will be throttled. The sum of request costs is then compared against pre-determined limits.
Throttling is based on a token bucket algorithm, which works by adding individual costs of requests. Identity and access service limits Pattern For example, if you are being throttled, you can begin with a call that requests 3 days of data and iterate with shorter timespans until your requests are no longer throttled. Then, iterate through the next timespan until you have all the records you need. If you need a broad set of Azure AD reporting data, use $filter on the createdDateTime to limit the amount of sign-in events you query in a single call.If you only need a certain type of event or a subset of users, for example, filter out other events using the $filter and $select query parameters to reduce the size of your response object and the risk of throttling. Use filters to target your query to just the data you need.
