This API is used to modify the slave availability zone of a cluster.
A maximum of 20 requests can be initiated per second for this API.
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common Params. The value used for this API: ModifyClusterSlaveZone. |
| Version | Yes | String | Common Params. The value used for this API: 2019-01-07. |
| Region | Yes | String | Common Params. For more information, please see the list of regions supported by the product. This API only supports: ap-bangkok, ap-beijing, ap-chengdu, ap-chongqing, ap-guangzhou, ap-hongkong, ap-jakarta, ap-nanjing, ap-seoul, ap-shanghai, ap-shenzhen-fsi, ap-singapore, ap-tokyo, eu-frankfurt, na-ashburn, na-siliconvalley, sa-saopaulo. |
| ClusterId | Yes | String | Cluster Id. |
| OldSlaveZone | Yes | String | Old secondary AZ |
| NewSlaveZone | Yes | String | New secondary AZ |
| BinlogSyncWay | No | String | binlog synchronization mode. Default value: async. Available values: sync, semisync, async |
| SemiSyncTimeout | No | Integer | Semi-sync timeout period, in milliseconds. To ensure business stability, semi-sync replication has a degradation logic. If the primary AZ cluster exceeds this timeout period while waiting for the standby AZ cluster to confirm a transaction, the replication method degrades to asynchronous replication. The minimum is set to 1000 ms, with support up to 4294967295 ms. Default: 10000 ms. |
| Parameter Name | Type | Description |
|---|---|---|
| FlowId | Integer | Async FlowId |
| RequestId | String | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
