TiDB Cloud limits how many of each kind of component you can create in a TiDB Dedicated cluster, and the common usage limitations of TiDB. In addition, there are some organization-level quotas to limit the amount of resources created by users to prevent from creating more resources than you actually need. These tables outline limits and quotas.
Note
If any of these limits or quotas present a problem for your organization, please contact TiDB Cloud Support.
