Description: A Global Table in the context of AWS CloudFormation refers to a DynamoDB table that is automatically replicated across multiple regions. This feature allows applications to access data quickly and efficiently, regardless of the user’s geographical location. Global Tables are particularly useful for applications that require high availability and low latency, as they enable data to be available in multiple regions simultaneously. Each global table consists of local tables in each region, which are automatically synchronized to ensure data consistency. This replication occurs asynchronously, meaning changes in one region propagate to others, allowing applications to continue functioning even if one region experiences issues. Additionally, Global Tables offer features such as the ability to perform queries and write operations in any region, enhancing the flexibility and scalability of applications. In summary, Global Tables are a powerful solution for optimizing the performance and availability of globally distributed applications.
