You can call the DescribeTable operation to query the description of a table, such as the schema information, reserved read throughput, and reserved write throughput.
Prerequisites
An OTSClient instance is initialized. For more information, see Initialize an OTSClient instance.
A data table is created. For more information, see Create a data table.
API operation
// Query the description of a table by using the table name.
DescribeTable(request *DescribeTableRequest) (*DescribeTableResponse, error) Parameters
Parameter | Required | Description |
TableName | Yes | The name of the table |
Examples
The following sample code provides an example on how to query the max versions and time to live (TTL) of a table:
func DescribeTableSample(client *tablestore.TableStoreClient, tableName string){
describeTableReq := new(tablestore.DescribeTableRequest)
describeTableReq.TableName = tableName
describ, err := client.DescribeTable(describeTableReq)
if err != nil {
fmt.Println("failed to update table with error:", err)
} else {
fmt.Println("DescribeTableSample finished. Table meta:", describ.TableOption.MaxVersion, describ.TableOption.TimeToAlive)
}

You can call API operations to read and write data in a data table. For more information, see Basic operations on data.
You can update a table to modify the information about the table, such as the time to live (TTL) and max versions. For more information, see Update a table.
You can delete a data table that you no longer require. For more information, see Delete tables.
