Kinesis Firehose Overview

AWS Kinesis Firehose is a fully managed service that automatically collects, transforms, and loads streaming data into data lakes, data stores, and analytics services. It is the easiest way to reliably stream data into AWS.

• Data Streams: Continuous streams of data from various sources.
• Delivery Streams: The streams created to deliver data to endpoints.
• Transformations: Data can be transformed before loading into a destination.
• Destinations: Common destinations include Amazon S3, Redshift, and Elasticsearch.

1. Create a Delivery Stream

To create a delivery stream:

aws firehose create-delivery-stream --delivery-stream-name my-delivery-stream --s3-destination-configuration file://s3-config.json

2. Configure Amazon S3 as Destination

In the s3-config.json file, specify the S3 bucket and other configurations:

{
    "BucketARN": "arn:aws:s3:::my-bucket",
    "RoleARN": "arn:aws:iam::account-id:role/firehose_delivery_role",
    "Prefix": "data/",
    "ErrorOutputPrefix": "error/",
    "BufferingHints": {
        "SizeInMBs": 5,
        "IntervalInSeconds": 300
    }
}

3. Send Data

You can send data using AWS SDKs or directly via HTTP PUT requests.

aws firehose put-record --delivery-stream-name my-delivery-stream --record '{"Data":"my data"}'

4. Verify Data in S3

Check the specified S3 bucket to verify that data is being delivered.

• Use smaller buffer sizes for real-time applications.
• Implement data transformation for better analytics.
• Monitor delivery stream metrics using AWS CloudWatch.
• Ensure IAM roles have least privilege permissions.
