Assistant Professor Manos Athanassoulis wins CAREER award
Congratulations to Assistant Professor Manos Athanassoulis for winning a National Science Foundation CAREER award for building Robust LSM-based Data Stores.
Log-structured merge (LSM) trees are becoming the de facto standard for write-intensive storage layers for both production NoSQL data stores and relational systems. As LSM-based systems are used by various applications and deployed in shared infrastructure (e.g., public or private cloud), they are tasked to support a number of requirements varying from performance, to cost, and privacy, being robust to external requirements and the inherent workload unpredictability. At the heart of any LSM-based engine, we have the background re-organization mechanism (or compaction), the behavior of which affects essentially every aspect of the LSM-tree including write amplification, write throughput, point and range lookup performance, space amplification, and delete performance.
