Add rate-limiting to admin query/transact - #2887
Conversation
📝 WalkthroughWalkthroughThe change adds per-app and global admin rate-limit configuration lookup. Admin query and transaction handlers and permission checks consume the configured rate-limit buckets. ChangesAdmin rate limiting
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change adds limits to admin queries and transactions, but transaction preparation still occurs before rejection, unauthenticated guest traffic can exhaust an app’s administrator quota, and SSE query routes remain outside the limit. These gaps can waste server resources or deny legitimate admin operations, so the PR needs fixes or explicit owner acceptance before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

- Around line 148-153: Extend the admin rate-limit enforcement around the
permission-check route handlers for query and transaction operations, matching
the existing consume-user-rate-limit configuration used by query-post and
transact-post. Ensure /admin/query_perms_check and /admin/transact_perms_check
consume their corresponding configured buckets before performing work, while
preserving the existing app-id bucket key and endpoint-specific bucket names.

Adds the ability to rate limit admin query and transact.
The rate limit config is set through the
global-admin-rate-limitflag and can be tuned per app with theadmin-rate-limit-for-appflag, keyed by app_id.
