Switching to the DR Cluster
Function
This API is used to perform a DR switchover.
To perform a switchover when the DR cluster is running properly, you can click Switch to DR Cluster on the console.
You can perform a DR switchover when the DR task is in the Running state.
During a switchover, the original production cluster is not available.
Recovery Point Object (RPO) refers to the point in time to which a system and data must be restored after a disaster occurs. The key aspects are as follows:
Production cluster in the Available state: RPO = 0
Production cluster in the Unavailable state: A zero RPO may not be achieved, but data can at least be restored to that of the latest successful DR synchronization (Last DR Succeeded).
This function is available only for DWS 2.0 clusters.
