Confluent · Rate Limits

Confluent Rate Limits

Confluent enforces two distinct kinds of limit and it matters which one an agent hits. Request-rate and concurrency throttling returns 429 with headers; service quotas are resource COUNT ceilings (how many API keys, clusters, topics you may have) which surface as 402/400. Confluent publishes the throttling header contract precisely and the per-endpoint numeric rates not at all.

Confluent Rate Limits is the machine-readable rate-limit profile for Confluent on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests, concurrent-operations, connections-per-second, and api-keys.

The profile also includes response codes documented for throttled, quotaExceeded, quotaExceededKnownIssue, and serviceUnavailable.

Tagged areas include Rate Limiting, Quotas, Throttling, and Service Quotas.
