与 AWS SDK或CreateStream一起使用 CLI

以下代码示例演示如何使用 CreateStream

操作示例是大型程序的代码摘录,必须在上下文中运行。在以下代码示例中,您可以查看此操作的上下文:

using System; using System.Threading.Tasks; using Amazon.Kinesis; using Amazon.Kinesis.Model; /// <summary> /// This example shows how to create a new Amazon Kinesis stream. /// </summary> public class CreateStream { public static async Task Main() { IAmazonKinesis client = new AmazonKinesisClient(); string streamName = "AmazonKinesisStream"; int shardCount = 1; var success = await CreateNewStreamAsync(client, streamName, shardCount); if (success) { Console.WriteLine($"The stream, {streamName} successfully created."); } } /// <summary> /// Creates a new Kinesis stream. /// </summary> /// <param name="client">An initialized Kinesis client.</param> /// <param name="streamName">The name for the new stream.</param> /// <param name="shardCount">The number of shards the new stream will /// use.

创建数据流

以下 create-stream 示例创建一个名为 samplestream 的数据流,其中包含 3 个分片。

aws kinesis create-stream \ --stream-name samplestream \ --shard-count 3

此命令不生成任何输出。

PowerShell
用于 PowerShell

示例 1:创建新流。默认情况下,此 cmdlet 不返回任何输出,因此添加-PassThru 开关以返回提供给-StreamName 参数的值以供日后使用。

$streamName = New-KINStream -StreamName "mystream" -ShardCount 1 -PassThru
