We designed Aurora as a cloud-native relational database that gives customers the performance, availability, and scalability to meet the needs of their most demanding internet workloads. AWS has presented two papers at the conference about Aurora architecture, " Amazon Aurora: Design Considerations for High Throughput Cloud" in 2017 and " Amazon Aurora: On Avoiding Distributed Consensus for I/Os, Commits, and Membership Changes," in 2018. This wasn't the first time Aurora has made an appearance at the ACM SIGMOD Conference. The Aurora developers accepting the award (in my hometown of Amsterdam!) also shared a presentation about Aurora architectural innovation. This year's Systems Award was presented this week at the annual ACM SIGMOD Conference, where researchers and practitioners got together to explore cutting edge ideas. This year, SIGMOD has chosen the developers of the Amazon Aurora database system as the recipients of the 2019 ACM SIGMOD Systems Award for fundamentally redesigning relational database storage for cloud environments. Each year the group presents awards to recognize significant contributions in the field of data management. SIGMOD is a community of software developers, academic and industrial researchers, practitioners, and users specializing in large-scale data management problems and databases. The award recognizes "an individual or set of individuals for the development of a software or hardware system whose technical contributions have had significant impact on the theory or practice of large-scale data management systems." This week, the developers of Amazon Aurora have won the 2019 Association for Computing Machinery's (ACM) Special Interest Group on Management of Data (SIGMOD) Systems Award. Aurora development team wins the 2019 ACM SIGMOD Systems AwardĪ few months ago, I wrote the post " Amazon Aurora ascendant: How we designed acloud-native relational database," and now I'm excited to share some news about the people behind the service.Users can initiate the restoration from the API or the CLI, making it easy to integrate into their existing test framework.Amazon Aurora development team wins the 2019 ACM SIGMOD Systems Award | All Things Distributed It is expected that people will find additional use cases for the new feature, adds Barr, such as restoring a test database after running a test that makes changes to the database. In addition, other Aurora features such as cloning, backups, and restores continue to work on an instance that has been configured for backtrack. If a user has gone too far back, Barr says, it is possible to backtrack to a later time. This allows for quick access and recovery times measured in seconds.” “Enabling the backtrack feature provisions a FIFO buffer in the cluster for storage of LSNs. “Aurora uses a distributed, log-structured storage system (read Design Considerations for High Throughput Cloud-Native Relational Databases to learn a lot more) each change to your database generates a new log record, identified by a Log Sequence Number (LSN),” he writes. The new feature was announced in a blog post by Jeff Barr, chief evangelist for AWS. The feature is available now in all AWS Regions where Amazon Aurora runs. Users must opt-in when they create or restore a cluster they cannot enable it for a running cluster. This option applies to newly created MySQL-compatible Aurora database clusters and to MySQL-compatible clusters that have been restored from a backup. Backtrack can be enabled by customers for newly-launched Aurora database clusters by specifying how far back in time they want to rewind, and then using the database as usual. Amazon Web Services (AWS) has introduced Amazon Aurora Backtrack, a new feature that provides an “undo option” for a production database.
