Changefeed Billing
RCU cost
TiDB Cloud measures the capacity of changefeeds in TiCDC Replication Capacity Units (RCUs). When you create a changefeed for a cluster, you can select an appropriate specification. The higher the RCU, the better the replication performance. You will be charged for these TiCDC changefeed RCUs.
Number of TiCDC RCUs
The following table lists the specifications and corresponding replication performances for changefeeds:
Specification | Maximum replication performance |
---|---|
2 RCUs | 5,000 rows/s |
4 RCUs | 10,000 rows/s |
8 RCUs | 20,000 rows/s |
16 RCUs | 40,000 rows/s |
24 RCUs | 60,000 rows/s |
32 RCUs | 80,000 rows/s |
40 RCUs | 100,000 rows/s |
Price

Private Data Link cost
If you choose the Private Link or Private Service Connect network connectivity method, additional Private Data Link costs will be incurred. These charges fall under the Data Transfer Cost category.
The price of Private Data Link is $0.01/GiB, the same as Data Processed of AWS Interface Endpoint pricing and Consumer data processing of Google Cloud Private Service Connect pricing.
