    using System;
    using System.Collections.Generic;
    using System.Threading.Tasks;
    using Amazon.Kinesis;
    using Amazon.Kinesis.Model;

    /// <summary>
    /// Retrieves and displays a list of existing Amazon Kinesis streams.
    /// </summary>
    public class ListStreams
    {
        public static async Task Main(string[] args)
        {
            IAmazonKinesis client = new AmazonKinesisClient();
            var response = await client.ListStreamsAsync(new ListStreamsRequest());

            List<string> streamNames = response.StreamNames;

            if (streamNames.Count > 0)
            {
                streamNames
                    .ForEach(s => Console.WriteLine($"Stream name: {s}"));
            }
            else
            {
                Console.WriteLine("No streams were found.");
            }
        }
    }

CLI

AWS CLI

To list data streams

The following list-streams example lists all active data streams in the current account and region.

aws kinesis list-streams

Output:

{
    "StreamNames": [
        "samplestream",
        "samplestream1"
    ]
}

For more information, see Listing Streams in the Amazon Kinesis Data Streams Developer Guide.

Rust

SDK for Rust

Note

async fn show_streams(client: &Client) -> Result<(), Error> {
    let resp = client.list_streams().send().await?;

    println!("Stream names:");

    let streams = resp.stream_names;
    for stream in &streams {
        println!("  {}", stream);
    }

    println!("Found {} stream(s)", streams.len());

    Ok(())
}
