Kinesis consumer application in c++

Hi,

One of the approaches to create an Amazon Kinesis Consumer for C++ is to use the AWS SDK for C++. The SDK provides API's that you can use to create a consumer application for C++.

High level steps below,

1. Get AWS SDK for C++ on your work environment. You can download it from here: https://aws.amazon.com/sdk-for-cpp/
2. Create an Amazon Kinesis stream using the AWS Management Console or the AWS SDK for C++.
3. Create a Kinesis client object in your C++ application using the SDK API.
4. Use the client object to read data from the Kinesis stream using the GetRecords API. You can use the ShardIteratorType parameter to specify the position in the shard from which to start reading data.
5. Process the data received from the Kinesis stream in your C++ application.

A code sample is below, please customise it based on your requirements,

#include <aws/kinesis/KinesisClient.h>
#include <aws/core/utils/Outcome.h>
#include <aws/core/utils/logging/LogLevel.h>

using namespace Aws::Kinesis;
using namespace Aws::Utils::Logging;
using namespace Aws::Client;
using namespace Aws::Utils;

int main(int argc, char** argv)
{
    // Initialize the AWS SDK for C++
    Aws::SDKOptions options;
    Aws::InitAPI(options);

    // Set up the Kinesis client
    ClientConfiguration clientConfig;
    KinesisClient kinesis(clientConfig);

    // Set up the request to read data from the Kinesis stream
    GetRecordsRequest request;
    request.SetShardIterator("<shard-iterator>");
    request.SetLimit(100);

    // Read data from the Kinesis stream
    while (true)
    {
        GetRecordsOutcome outcome = kinesis.GetRecords(request);
        if (outcome.IsSuccess())
        {
            std::vector<Record> records = outcome.GetResult().GetRecords();
            for (const auto& record : records)
            {
                // Process the record data
                std::cout << record.GetData() << std::endl;
            }

            // Set the shard iterator to the next position
            request.SetShardIterator(outcome.GetResult().GetNextShardIterator());
        }
        else
        {
            // Handle the error
            std::cout << "Error reading data from Kinesis stream: " << outcome.GetError().GetMessage() << std::endl;
            break;
        }
    }

    // Shutdown the AWS SDK for C++
    Aws::ShutdownAPI(options);

    return 0;
}
