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 sample code provides an example on how to query information of a time series table:

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)
        }
    }
}
