SwitchInstanceVip

Last updated: 2024-12-04 11:18:51

    1. API Description

    Domain name for API request: redis.intl.tencentcloudapi.com.

    This API is used to swap the VIPs of instances for disaster recovery in DTS-based cross-AZ disaster recovery scenarios. After the swapping, the target instance becomes writable, the VIPs of the source and target instances are swapped, and the DTS synchronization task between the source and target instances is disconnected.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
