Manage TiDB Cloud Filesystem Usage Limits
You can create and use file systems in the TiDB Cloud Filesystem service without a credit card, but each free file system has tighter capacity limits. You can raise these limits after adding a credit card to your organization.
Usage limits for organizations without a credit card
When your organization has no credit card registered, the following limits apply to each free file system:
- One file system per region
- 2,000 files per file system
- 2 GiB of storage per file system
- 500 MiB maximum size for a single file
With a credit card, you can set higher limits and continue with pay-as-you-go usage. See TiDB Cloud Filesystem pricing for billing details.
View file system usage
To view the current usage of a file system, go to its overview page in the TiDB Cloud console and check the Usage area. For usage details, click Usage in the left navigation pane.
When a file system reaches a usage limit
When a file system reaches its storage or file count limit, existing files remain readable, but the file system stops accepting new writes. A single file cannot grow beyond the file size limit. The one-file-system-per-region limit applies when you create another file system in that region. The TiDB Cloud console shows a warning.
Update the usage limits
In the TiDB Cloud console, navigate to the File Systems page, select the Cloud Provider and Region for the file system, and click the name of your target file system.
On the overview page of the file system, click Edit Usage Limit in the Usage area.
Set maximum storage, file count, and file size as needed, then click Save.
If your organization has no credit card, these fields are disabled. Add a credit card to edit them and enable pay-as-you-go usage.
