History

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

It became possible to stop and start Aurora Clusters in September 2018.[4] In August 2018 Amazon began to offer a serverless version.[5]

In 2019 the developers of Aurora won the SIGMOD Systems Award for fundamentally redesigning relational database storage for cloud environments.[6]

Features

Aurora automatically allocates database storage space in 10-gigabyte increments, as needed, up to a maximum of 64 terabytes.[7] Aurora offers automatic, six-way replication of those chunks across multiple locations for improved availability and fault-tolerance.

Aurora provides users with performance metrics, such as query throughput and latency.[8] It provides fast database cloning.[9]

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. Not all MySQL options and features are available: as of September 2016, Amazon Aurora is compatible with MySQL 5.6 and 5.7. It supports InnoDB as a storage engine.[10]

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".[10] Other independent tests have shown that Aurora performs better than competing technologies on some, but not all, combinations of workload and instance type.

gollark: I see. Same sort of effect.
gollark: Previous version is deprecated, new version is unreleased…
gollark: *brain melting noises*
gollark: This may be a bad project for you.
