Cloud Native databases architecture has evolved to leverage the elasticity, reliability and scalability available in the cloud. There is a growing trend to leverage object storage systems such as AWS S3 for architecting cost-effective, performant and scalable systems. S3 is a large-scale, high throughput key-value storage system, which it trades for a slightly higher latency. In this session we will present techniques used to leverage S3 for a low latency scalable distributed SQL database, in particular how to get around S3’s high latency by leveraging a novel new LSM Cloud Storage Engine that uses EBS as a cache to lower latency.
