At the re:Invent conference, AWS introduced Aurora DSQL, a serverless, distributed SQL database designed for virtually unlimited scalability.
It promises high availability (99.999% for multi-region setups), PostgreSQL compatibility, and 4x faster read and write performance compared to other distributed SQL databases.
Aurora DSQL eliminates database sharding and scales reads and writes independently. With strong consistency, the database ensures all regions display the same data at the same time.
It also uses an active-active architecture for resiliency, ensuring continuous availability.
AWS’s innovative approach decouples transaction processing from storage, leveraging synchronized time to achieve microsecond-level consistency across regions.
