Last month at OpenLate, Nate Slater from Amazon Web Services gave a tech talk about Aurora, their new MySQL-compatible relational database system. While it functions as a drop-in replacement for MySQL 5.6, the way the system works has been completely rearchitected for multiple availability zones, better crash recovery, and higher throughput. The AWS team did this by using techniques like log-structured storage, quorum votes for read and write transactions, and smarter cache invalidation that keeps replication lag in the millisecond range.
