Today, we are announcing the preview of Amazon Aurora Limitless Database, 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 you to increase the read capacity of your Aurora cluster beyond the limits of what a single database instance can provide. Now, Aurora Limitless Database scales write throughput and storage capacity of your 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.
