删除时间线元数据

前提条件

• 已写入时序数据。具体操作，请参见写入时序数据。
• 已初始化TimeseriesClient。具体操作，请参见初始化。

参数

timeseriesKey用于标识一个时间线，您可以传入多个timeseriesKey来删除多条时间线的元数据。详细参数说明请参见下表。

示例

以下示例用于删除时序表中的部分时间线。

func DeleteTimeseriesMetaSample(tsClient *tablestore.TimeseriesClient, timeseriesTableName string) {
    fmt.Println("[Info]: Begin to delete timeseries meta: ", timeseriesTableName)
    // 构造删除时间线元数据的请求。
    deleteTimeseriesMetaRequest := tablestore.NewDeleteTimeseriesMetaRequest(timeseriesTableName) 
    for i := 0; i < 10; i++ {
        timeseriesKey := tablestore.NewTimeseriesKey()
        timeseriesKey.SetMeasurementName("cpu")
        timeseriesKey.SetDataSource("host_" + strconv.Itoa(i))
        timeseriesKey.AddTag("region", "hangzhou")
        timeseriesKey.AddTag("os", "Ubuntu16.04")
        deleteTimeseriesMetaRequest.AddTimeseriesKeys(timeseriesKey)
    }
    deleteTimeseriesMetaResponse, err := tsClient.DeleteTimeseriesMeta(deleteTimeseriesMetaRequest)
    if err != nil {
        fmt.Println("[Error]: Failed to delete timeseries meta with error: ", err)
        return
    }
    fmt.Println("[Info]: DeleteTimeseriesMeta finished! RequestId: ", deleteTimeseriesMetaResponse.RequestId)
}
