DynamoDB – A Tech Ref

DynamoDB and DAX

DAX (DynamoDB Accelerator) is a fully managed, in-memory caching service for DynamoDB that can significantly improve read performance by reducing the number of requests to DynamoDB. DAX is designed to work with DynamoDB, and it provides a fast, scalable, and highly available caching layer that sits between your application and DynamoDB.

DAX can significantly improve read performance by reducing the number of requests to DynamoDB and caching frequently accessed data in memory. By using DAX, you can improve the performance and cost-effectiveness of your application while minimizing infrastructure management.

DynamoDB Performance and Optimizations

DynamoDB is designed to provide high performance and scalability, even at scale. It is a highly available and durable NoSQL database service that can handle large volumes of data and requests with low latency.

DynamoDB is a distributed database service that uses sharding to partition data across multiple servers called nodes. Each node is responsible for storing a subset of the data, and the partition key is used to determine which node stores the data. This allows DynamoDB to scale horizontally by adding more nodes to the cluster as the data and request volume grows.

Intro to AWS DynamoDB

AWS DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It is a high-performance, scalable, and highly available database that can handle millions of requests per second and can automatically partition and re-partition data across a cluster of machines.

DynamoDB allows you to store and retrieve any amount of data and serve any level of request traffic, and provides a flexible and efficient data model that supports both document and key-value store paradigms. It also offers advanced features such as automated backups, global replication, and fine-grained access control.
