Ra3 4xlarge pricing3/1/2024 ![]() If you’re migrating from DC2 or DS2 node types to RA3, you can use our recommendations on node count and type as a benchmark. To perform this comparison, you can use the Amazon Redshift sizing calculator recommendations in the previous step as a benchmark and test other configurations with it in parallel to compare performance. This utility helps evaluate performance of your queries using different Amazon Redshift cluster configurations in parallel and compares the end results to find the best cluster configuration that meets your need. If you have stringent service level agreements (SLAs) for query performance in your Amazon Redshift cluster or you want to explore different Amazon Redshift configurations based on the price/performance of your workload, you can use the Amazon Redshift Node Configuration Comparison utility. Amazon Redshift Node Configuration Comparison utility You can use this recommendation to create your Amazon Redshift cluster and quickly get started with your workload to gain insights from your data in the Amazon Redshift data warehouse. If your data is not time based, what percentage of data do your queries access frequentlyīased on your response, you receive a recommended node configuration, as shown in the following screenshot.If your data is time based, how many months of data does the data warehouse contain and how many months are frequently queried on that data.The compressed or uncompressed size of your total dataset.In this wizard, you need to provide the following information: ![]() This option allows you to get an estimate of your cluster configuration based on your data size and data access frequency. The Amazon Redshift console provides the Help me choose option when you create a new Amazon Redshift cluster. ![]() We describe this utility in detail later in this post. Before doing that, you can use the utility to evaluate the new cluster’s performance by replaying your past workloads too, which integrates with the Amazon Redshift Simple Replay utility to evaluate performance metrics for different Amazon Redshift configurations to meet your needs. If you’re already using Amazon Redshift and want to migrate from your existing DC2 or DS2 instances to RA3, you may follow our recommendations on node count and type when upgrading. Use the Amazon Redshift Node Configuration Comparison utility to find the right configuration for your cluster based on your query performance expectation for sequential or concurrently running queries.Use the Amazon Redshift sizing calculator on the Amazon Redshift console, which estimates your cluster configuration based on data size and data access frequency.Node sizeĪ very common question we get from customers is “Which RA3 instance type and number of nodes should we choose for our workload?” In this post, we answer that question with the following two-step process: Many customers start their workload on Amazon Redshift with RA3 instances as their default choice, which currently offers three node sizes. Amazon Redshift RA3 with managed storage is the newest instance type in Amazon Redshift, which allows you to scale and pay for compute and storage independently, and also allows advanced features like AQUA (Advanced Query Accelerator), cross-cluster data sharing, and cross-Availability Zone cluster relocation. This blog post will be updated soon with the changes related to the latest release.Īmazon Redshift is a fast, fully managed, widely popular cloud data warehouse that offers different node types to meet the flexible workload patterns of our customers. If you want to explore only Amazon Redshift Provisioned configurations based on your workload, please continue to follow steps as outlined in this blog below. ![]() If you want to either explore different Amazon Redshift Serverless configurations or combination of Amazon Redshift Provisioned and Serverless configurations based on your workload, please follow instructions as outlined in this Github repo. The Amazon Redshift Node Configuration Comparison utility latest release now supports Amazon Redshift Serverless to test your workload performance. February 2023: This post was reviewed and updated to include support for Amazon Redshift Serverless.
