Write modes for global tables - AWS Prescriptive Guidance

Write modes for global tables

Global tables are always active-active at the table level. However, you might want to treat them as active-passive by controlling how you route write requests. For example, you might decide to route write requests to a single Region to avoid potential write conflicts.

There are three main managed write patterns, as explained in the next three sections. You should consider which write pattern fits your use case. This choice affects how you route requests, evacuate a Region, and handle disaster recovery. The guidance in later sections depends on your application’s write mode.
