About the Project

This application is built using SST v3, which provides a powerful framework for building serverless applications.

It showcases DynamoDB Global Tables for multi-region data replication.

The app allows you to add items to DynamoDB tables in different regions and observe the replication in real-time.

When a new item is added to the US East 1 region, it is automatically replicated to the EU West 1 region. This is also true for the other way around.

As the items are immediately reloaded afterward, sometimes you can see that the item is not immediately available in the other region.
