This document describes the billing details for changefeeds in TiDB Cloud Dedicated.
TiDB Cloud Dedicated 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.
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 |
| 64 RCUs | 160,000 rows/s |
| 96 RCUs | 240,000 rows/s |
| 128 RCUs | 320,000 rows/s |
| 192 RCUs | 480,000 rows/s |
| 256 RCUs | 640,000 rows/s |
| 320 RCUs | 800,000 rows/s |
