This will take a few minutes to complete, at which point you can Open in Apache Zeppelin. Once the application has been created, select Start to start the Apache Flink application. We will keep the default settings for the application, and we can scale up as needed. Choose an AWS Glue Database to store the metadata around your sources and destinations used by Kinesis Data Analytics Studio.You can create a custom role for specific use cases using the IAM Console. Enter the name of your Studio notebook, and let Kinesis Data Analytics Studio create an AWS Identity and Access Management (IAM) role for this.Select the Studio tab on the main page, and select Create Studio Notebook.Open the AWS Management Console and navigate to Amazon Kinesis Data Analytics for Apache Flink.You can start interacting with your data stream by following these steps: region us-east-1 Creating a Kinesis Data Analytics Studio notebook Your data stream will be named input-stream. To create the data stream, use the following Kinesis create-stream AWS CLI command. For console instructions, see Creating and Updating Data Streams in the Kinesis Data Streams Developer Guide. You can create these streams using either the Amazon Kinesis console or the following AWS Command Line Interface (AWS CLI) command. To follow this guide and interact with your streaming data, you will need a data stream with data flowing through. We will use a Kinesis Data Stream for this example, as it is the quickest way to begin. Kinesis Data Analytics Studio is also compatible with Amazon Managed Streaming for Apache Kafka (Amazon MSK), Amazon Simple Storage Service (Amazon S3), and various other data sources supported by Apache Flink. In this post, we will introduce you to Kinesis Data Analytics Studio and get started querying data interactively from an Amazon Kinesis Data Stream using the Python API for Apache Flink (Pyflink). Furthermore, it accelerates developing and running stream processing applications that continuously generate real-time insights. Kinesis Data Analytics Studio combines the ease-of-use of Apache Zeppelin notebooks, with the power of the Apache Flink processing engine, to provide advanced streaming analytics capabilities in a fully-managed offering. It’s highly available and scalable, and it delivers high throughput and low latency for stream processing applications.Ĭustomers running Apache Flink workloads face the non-trivial challenge of developing their distributed stream processing applications without having true visibility into the steps conducted by their application for data processing. Apache Flink is an open-source framework and engine for processing data streams. ![]() Just a few clicks in the AWS Management console lets customers launch a serverless notebook to query data streams and get results in seconds. Kinesis Data Analytics reduces the complexity of building and managing Apache Flink applications. Amazon Kinesis Data Analytics Studio makes it easy for customers to analyze streaming data in real time, as well as build stream processing applications powered by Apache Flink using standard SQL, Python, and Scala. ![]()
