/**
 * <p>Get information about a single parameter by specifying the parameter name.</p>
 *          <p>Parameter names can't contain spaces. The service removes any spaces specified for the
 *    beginning or end of a parameter name. If the specified name for a parameter contains spaces
 *    between characters, the request fails with a <code>ValidationException</code> error.</p>
 *          <note>
 *             <p>To get information about more than one parameter at a time, use the <a>GetParameters</a> operation.</p>
 *          </note>
 *          <note>
 *             <p>Parameter Store throughput defines the number of API transactions per second (TPS) that
 *     Systems Manager can process. This applies to <code>GetParameter</code>,
 *     <code>GetParameters</code>, and <code>PutParameter</code> API calls for your Amazon Web Services account and
 *     Amazon Web Services Region. By default, Parameter Store is configured with a standard throughput quota suitable
 *     for low- to moderate-volume workloads. Applications that retrieve configuration data infrequently
 *     or operate at smaller scale can use this default setting without additional cost.</p>
 *             <p>For higher-volume workloads, you can enable higher throughput. This increases the maximum
 *     number of supported transactions per second for your account and Region. Increased throughput
 *     supports applications and workloads that need concurrent access to multiple parameters. If you
 *     experience <code>ThrottlingException: Rate exceeded</code> errors, enable higher throughput. For
 *     more information, see <a href="https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-throughput.html">Changing Parameter Store
 *      throughput</a>.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SSMClient, GetParameterCommand } from "@aws-sdk/client-ssm"; // ES Modules import
 * // const { SSMClient, GetParameterCommand } = require("@aws-sdk/client-ssm"); // CommonJS import
 * // import type { SSMClientConfig } from "@aws-sdk/client-ssm";
 * const config = {}; // type is SSMClientConfig
 * const client = new SSMClient(config);
 * const input = { // GetParameterRequest
 *   Name: "STRING_VALUE", // required
 *   WithDecryption: true || false,
 * };
 * const command = new GetParameterCommand(input);
 * const response = await client.send(command);
 * // { // GetParameterResult
 * //   Parameter: { // Parameter
 * //     Name: "STRING_VALUE",
 * //     Type: "String" || "StringList" || "SecureString",
 * //     Value: "STRING_VALUE",
 * //     Version: Number("long"),
 * //     Selector: "STRING_VALUE",

 * //     LastModifiedDate: new Date("TIMESTAMP"),
 * //     ARN: "STRING_VALUE",
