Amazon Aurora is a relational database service developed and offered by Amazon Web Services beginning in October 2014.[1][2] Aurora is available as part of the Amazon Relational Database Service (RDS).

History

Aurora offered MySQL compatible service upon its release in 2014. It added PostgreSQL compatibility in October 2017.[3]

In August 2017, Aurora Fast Cloning (copy-on-write) feature was added allowing customers to create copies of their databases.[4] In May 2018, Aurora Backtrack was added which allows developers to rewind database clusters without creating a new one.[5] It became possible to stop and start Aurora Clusters in September 2018.[6] In August 2018, Amazon began to offer a serverless version.[7][8]

In 2019 the developers of Aurora won the SIGMOD Systems Award for fundamentally redesigning relational database storage for cloud environments.[9]

Features

Aurora automatically allocates database storage space in 10-gigabyte increments, as needed, up to a maximum of 128 terabytes.[10] Aurora offers automatic, six-way replication of those chunks across three availability zones for improved availability and fault-tolerance.[11]

Aurora provides users with performance metrics, such as query throughput and latency.[12] It provides fast database cloning.[13]

Aurora Multi-Master allows creation of multiple read-write instances in an Aurora database across multiple availability zones, which enables uptime-sensitive applications to achieve continuous write availability through instance failure.[14]

MySQL compatibility

Amazon designed Aurora to be compatible with MySQL, meaning that tools for querying or managing MySQL databases (such as the mysql command-line client and the MySQL Workbench graphical user-interface) can be used. As of December 2021, Amazon Aurora is compatible with MySQL 5.6, 5.7, and 8.0.[15] It supports InnoDB as a storage engine.[16]

Performance

Amazon claims fivefold performance improvements on benchmarking tests over MySQL on the same hardware, due to "tightly integrating the database engine with an SSD-based virtualized storage layer purpose-built for database workloads, reducing writes to the storage system, minimizing lock contention and eliminating delays created by database process threads".[16] Other independent tests have shown that Aurora performs better than competing technologies on some, but not all, combinations of workload and instance type.[citation needed]
