--- title: Amazon DAX description: >- A managed, in-memory cache for DynamoDB that can boost performance by up to 10 times. breadcrumbs: Docs > Integrations > Amazon DAX --- # Amazon DAX Integration version1.0.0 ## Overview{% #overview %} Amazon DynamoDB Accelerator (DAX) is a DynamoDB-compatible caching service that enables you to benefit from fast in-memory performance for demanding applications. Enable this integration to see all your Amazon DynamoDB Accelerator (DAX) metrics in Datadog. ## Setup{% #setup %} ### Installation{% #installation %} If you haven't already, set up the [Amazon Web Services integration](https://docs.datadoghq.com/integrations/amazon_web_services.md) first. ### Metric collection{% #metric-collection %} 1. In the [AWS integration tile](https://app.datadoghq.com/integrations/amazon-web-services), ensure that `DynamoDBAccelerator` is checked under metric collection. 1. Install the [Datadog - Amazon DynamoDB Accelerator integration](https://app.datadoghq.com/integrations/amazon-DynamoDB-accelerator). ## Data Collected{% #data-collected %} ### Metrics{% #metrics %} |
