Service Quotas for Confluent Cloud

Confluent Cloud limits the number of different resources you can create. Some limits can be raised on request, but there are hard limits for all resources. To request an increase for a limit, contact Confluent Support.

Important

Your organization’s applied limits may be different from the default limits, due to previous requests from your organization. Check your organization’s applied limits by using the Quotas API.
