Tablestore:Query the description of a table

Prerequisites

• OTSClient is initialized. For more information, see Initialization.

• A table is created.

Parameters

Example

The following sample code provides an example on how to query the schema information, optional configurations, reserved read throughput, and reserved write throughput of a table:

private static void describeTable(SyncClient client) {
    // Specify the name of the table. 
    DescribeTableRequest request = new DescribeTableRequest("<TABLE_NAME>");
    DescribeTableResponse response = client.describeTable(request);
    TableMeta tableMeta = response.getTableMeta();
    System.out.println("Table name:" + tableMeta.getTableName());
    System.out.println("Primary key information:");
    for (PrimaryKeySchema primaryKeySchema : tableMeta.getPrimaryKeyList()) {
        System.out.println(primaryKeySchema);
    }
    TableOptions tableOptions = response.getTableOptions();
    System.out.println("Table TTL:" + tableOptions.getTimeToLive());
    System.out.println("Maximum number of data versions:" + tableOptions.getMaxVersions());
    // You can view the encryption configurations of a table only if the table is an encrypted table. If the table is not an encrypted table, this parameter is not returned. 
    System.out.println("Encryption configurations:" + response.getSseDetails());
    ReservedThroughputDetails reservedThroughputDetails = response.getReservedThroughputDetails();
    System.out.println("Reserved read throughput:"
            + reservedThroughputDetails.getCapacityUnit().getReadCapacityUnit());
    System.out.println("Reserved write throughput:"
            + reservedThroughputDetails.getCapacityUnit().getWriteCapacityUnit());
}
