DynamoDB Global tables provide a fully managed, multi-Region, and multi-active database that delivers fast, local, read and write performance for massively scaled, global applications.
Global tables replicate the DynamoDB tables automatically across the choice of AWS Regions and enable reads and writes on all instances.
DynamoDB global table consists of multiple replica tables (one per AWS Region). Every replica has the same table name and the same primary key schema. When an application writes data to a replica table in one Region, DynamoDB propagates the write to the other replica tables in the other AWS Regions automatically.
Global tables enable the read and write of data locally providing single-digit-millisecond latency for the globally distributed application at any scale.
Global tables enable the applications to stay highly available even in the unlikely event of isolation or degradation of an entire Region.
AWS Certification Exam Practice Questions
Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated
Open to further feedback, discussion and correction.
