description: >-
  Published Dremio Cloud rate limits and resource quotas, read from Dremio's own Limits page on
  2026-09-06. This replaces the 2026-05-04 scaffold, whose header names and per-tier numbers were
  bulk-sweep defaults that Dremio never published.
scope_note: >-
  Dremio states that rate limits are enforced on a single IP address and apply across all
  organizations and projects — the throttle is per source IP, not per API key or per account.
  That is unusual and matters to an agent: several agents sharing an egress IP share one budget.
headers:
  limit: null
  remaining: null
  reset: null
  retryAfter: null
  policy: null
headers_note: >-
  Dremio documents no rate-limit response headers and no exhaustion status code. Checked
  2026-09-06 on the Limits page and the API Reference overview — the numbers are published as
  documentation only, with no runtime signal. Recorded null rather than assuming the common
  X-RateLimit-* set, which is what the previous scaffold did.
