Get started with Amazon Aurora DSQL
summary
Amazon Aurora DSQL is a Postgres-based serverless relational database that autodiscovers and partitions storage, scaling from Aurora’s 128 TB limit toward petabyte-class capacity, and assigns each connection a lightweight query processor so concurrent transactions don’t block each other. It uses a distributed journal, adjudicators for snapshot isolation, and a crossbar to sequence writes, providing Amazon Aurora DSQL as a multi-Region active-active system with synchronous replication and per-commit cross-region durability.
