Cost and Limitations
Free Quota
We’re offering a free quota up to the first 5 clusters created in each Organization. If you need to create the 6th cluster, you need to create a Scalable Cluster. For this, you’ll be required to provide a credit card and set a Spending Limit. But if you delete some of your previous clusters before creating the 6th, the new cluster will still have a free quota. In other words, customers can enjoy the free quota for up to 5 clusters, whether it’s Free Cluster or Scalable Cluster.
Free Quota will be issued monthly to serverless clusters that meet these qualifications. With the free quota, customers can store 5 GiB of row-based data, 5 GiB of columnar data, and consume 50 million RUs for one month.
In total, each Organization can get 25 GiB of row storage, 25 GiB of column storage, and 250M Request Units (RUs) for free per month. Customers can take advantage of this offer and optimize your operations without worrying about initial costs.
Spending Limit
The “Spending Limit” refers to the maximum amount of money that you are willing to spend on a particular workload in a month. It is a cost-control mechanism that enables you to set a budget for your TiDB Serverless clusters. For Scalable clusters, the spending limit must be set to a minimum of $0.01. Also, the scalable cluster can have a free quota if it meets the qualifications. The scalable cluster with a free quota will consume the free quota first.
Note: It is impossible to set a spending limit value lower than the amount already spent for the current month.
Throttled
A Scalable cluster will not be throttled unless the spending limit is reached. Once the spending limit is reached, the cluster immediately denies any new connection attempts until the quota is increased or the usage is reset at the start of a new month. Existing connections established before reaching the quota will remain active but will experience throttling.
If the free quota of a Free cluster is exhausted within the month, the cluster will automatically be throttled. This limit will remain in place until the customer upgrade it to Scalable cluster or until the next month.
In this way, customers can ensure basic business continuity without paying additional fees. At the same time, customers can adjust the spending limit according to their needs to control their usage and costs.
Billing Cycle
Each TiDB Cloud bill, corresponding to the previous month’s usage, is finalized at the start of every new month. This finalized bill is then charged to your default payment method, typically occurring between the 3rd and 9th day of the respective month. If your usage within the current month reaches or exceeds $250, an automatic charge will be initiated. Please note that the billing cycle operates strictly in accordance with the UTC (+00:00) time zone.
