Request Capacity Unit
What is a Request Capacity Unit (RCU)
A Request Capacity Unit (RCU) is a unit of measure used to represent the provisioned compute capacity for your TiDB Cloud Premium instance. One RCU provides a fixed amount of compute resources that can process a certain number of RUs-per-second. The number of RCUs you provision determines your cluster’s baseline performance and throughput capacity.
1 RCU represents sustained RUs-per-second capacity. A baseline of X RCU entitles the tenant to X RU/s averaged over 1-minute windows (or comply with our minimal calculation window).
RCU Pricing Detail
Minimum usage requirement: To ensure high availability and resource reservation, a Minimum Billing RCU is automatically established based on your Maximum RCU setting. If your actual consumption is lower than this threshold, the minimum value will be billed to cover the baseline reserved capacity.

Backup
TiDB Cloud Premium ensures your data is protected through a robust suite of backup options, including Automatic, Manual, and Continuous Log Backups for Point-in-Time Recovery (PITR).
These backups consume cloud storage. TiDB Cloud will charge you based on the capacity of backups and how long you stored the backups per month.
Note: We are currently offering a special package rate in the Public Preview phase for Continuous Log Backups (PITR). Please contact your sales representative for detailed pricing and eligibility.

Network Egress
TiDB Cloud exclusively charges for outbound data transfer (Egress), while all inbound traffic (Ingress) remains free of charge. These egress fees apply whenever data leaves the TiDB Cloud environment or crosses specific network boundaries, including data transferred to your applications via the public internet or through private networking channels such as VPC Peering and Private Link.

Cost and Limitations
Throttling
For TiDB Cloud Premium clusters, the throttling policy is based on the maximum Request Capacity Units (RCUs). When the workload exceeds the maximum RCU capacity, the cluster will automatically throttle incoming requests to maintain stability. This ensures predictable performance while protecting the cluster from overload.
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 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 $500, an automatic charge will be initiated. Note that the billing cycle operates strictly in accordance with the UTC (+00:00) time zone.
