AWS Announces Preview of Amazon Aurora Limitless Database

AWS announced a preview of Amazon Aurora Limitless Database is now available—a new capability supporting automated horizontal scaling to process millions of write transactions per second and manage petabytes of data in a single Aurora database.

Amazon Aurora read replicas allow users to increase the read capacity of their Aurora cluster beyond the limits of what a single database instance can provide.

Now, Aurora Limitless Database scales write throughput and storage capacity of users’ database beyond the limits of a single Aurora writer instance. The compute and storage capacity that is used for Limitless Database is in addition to and independent of the capacity of your writer and reader instances in the cluster.

With Limitless Database, users can focus on building high-scale applications without having to build and maintain complex solutions for scaling your data across multiple database instances to support your workloads. Aurora Limitless Database scales based on the workload to support write throughput and storage capacity that, until today, would require multiple Aurora writer instances.

Limitless Database has a two-layer architecture consisting of multiple database nodes, either transaction routers or shards.

Shards are Aurora PostgreSQL DB instances that each store a subset of the data for the database, allowing for parallel processing to achieve higher write throughput. Transaction routers manage the distributed nature of the database and present a single database image to database clients.

Transaction routers maintain metadata about where data is stored, parse incoming SQL commands and send those commands to shards, aggregate data from shards to return a single result to the client, and manage distributed transactions to maintain consistency across the entire distributed database.

All the nodes that make up the Limitless Database architecture are contained in a DB shard group. The DB shard group has a separate endpoint where your access your Limitless Database resources.

To get started with a preview of Aurora Limitless Database, you can sign up today and will be invited soon.

The preview runs in a new Aurora PostgreSQL cluster with version 15 in the AWS U.S. East (Ohio), U.S. East (N. Virginia), U.S. West (Oregon), Asia Pacific (Tokyo), and Europe (Ireland) Regions.
