Amazon Aurora DSQL
#59 · Level 2 · Scaling and resilience · DatabaseConcept
Section titled “Concept”Amazon Aurora DSQL is a serverless, distributed SQL database that can run in several Regions at once. It is compatible with PostgreSQL, so you can use familiar SQL and many PostgreSQL tools. You don’t choose servers or instances; it scales up and down on its own with the load. In a multi-Region setup you can read and write from several Regions at once, and the data stays consistent everywhere. It is part of the Aurora family, but its internal design is different from regular Aurora.
