Tablestore:Query information of a time series table

Prerequisites

• A time series table is created. For more information, see Create a time series table.

• A TimeseriesClient instance is initialized. For more information, see Initialize an OTSClient instance.

Parameters

Example

The following example calls DescribeTimeseriesTable to retrieve the time series table metadata, including the table name, time to live (TTL), and analytical store information.

func DescribeTimeseriesTableSample(client *tablestore.TimeseriesClient, timeseriesTableName string) {
    fmt.Println("[Info]: Begin to require timeseries table description!")
    describeTimeseriesTableRequest := tablestore.NewDescribeTimeseriesTableRequset(timeseriesTableName) // Construct a request and specify the name of the time series table.

    describeTimeseriesTableResponse, err := client.DescribeTimeseriesTable(describeTimeseriesTableRequest)
    if err != nil {
        fmt.Println("[Error]: Failed to require timeseries table description!")
        return
    }
    fmt.Println("[Info]: DescribeTimeseriesTableSample finished. Timeseries table meta: ")
    fmt.Println("[Info]: TimeseriesTableName: ", describeTimeseriesTableResponse.GetTimeseriesTableMeta().GetTimeseriesTableName())
    fmt.Println("[Info]: TimeseriesTable TTL: ", describeTimeseriesTableResponse.GetTimeseriesTableMeta().GetTimeseriesTableOPtions().GetTimeToLive())
    //If you have created an analytical store for the time series table, you can use the following code to obtain the analytical store information.
    analyticalStores := describeTimeseriesTableResponse.GetAnalyticalStores()
    for _, analyticalStore := range analyticalStores {
        fmt.Println("[Info]: AnalyticalStoreName: ", analyticalStore.StoreName)
        if analyticalStore.TimeToLive != nil {
            fmt.Println("[Info]: TimeToLive: ", *analyticalStore.TimeToLive)
        }
        if analyticalStore.SyncOption != nil {
            fmt.Println("[Info]: SyncOption: ", *analyticalStore.SyncOption)
        }
    }
}
