TiDB Serverless Pricing Details

Cost and Limitations

Free Quota

We’re offering a free quota up to the first 5 clusters created in each Organization. If you create a 6th cluster, you’ll need to add a credit card and set a Spending Limit to use it. 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.

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, 5GiB of columnar data, and consume 50 million RUs for one month. Of course, customers can also freely allocate these quotas to achieve equivalent operations.

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 allows you to set a budget for your serverless clusters. When the spending limit of a cluster is greater than 0, the cluster is considered a paid cluster. Also, the paid cluster can have a free quota if it meets the qualifications. The paid 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

If a customer sets a spending limit for a cluster, the cluster will not be throttled unless the spending limit is reached. Once the spending limit is reached, the read and write operation on this cluster will be throttled to 10 RU/s. This limit will remain in place until the next month or until the customer sets a larger spending limit.

If a cluster does not set a spending limit, and the free quota for the cluster is exhausted within the month, the cluster will automatically be throttled to 10 RU/s. This limit will remain in place until the customer sets a spending limit greater than 0 or until the next month.

In this way, customers can continue to use the basic functions of the system 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.
