Query regarding Rate limiting

[Abhishek Chauhan]

Regarding the new rate limiting Jira is planning to impose, https://developer.atlassian.com/cloud/jira/platform/rate-limiting/ . I have following queries.

1. What is the request-per-second quota for API calls under each cost budget (e.g., App, App + User, User, Anonymous)?

2. What is the allowed request volume over the longer interval (for example, per hour) under the quota limit and how does it relate to the burst limit?

3. What is the reset or ‘cool-off’ period once a rate limit is hit (i.e., after a 429 response)? What is the maximum ‘Retry-After’ or time until the budget resets?

4. Are the quotas and burst limits fixed or do they vary by product edition, tenant size (number of users), or app type?

5. How are different cost budgets (User, App, App + User, Anonymous) defined in terms of the limits — are they separate buckets?

6. In the header response X-RateLimit-Limit, what time window does that represent (per second, per minute, per hour)?

7. When the doc says ‘We reserve the right to adjust limits at any time,’ how will I be notified of changes?

8. If my Java application is making the calls to the Jira APIs using the basic authentication, then under which quota does it get considered ? ( e.g., App, App + User, User, Anonymous )
