Parallel shared-nothing data management systems have been widely used to exploit a cluster of machines for efficient and scalable data processing. When a cluster needs to be dynami…
Efficiently Reclaiming Space in a Log Structured Store
David Lomet, Chen Luo
A log structured store uses a single write I/O for a number of diverse and non-contiguous pages within a large buffer instead of using a write I/O for each page separately. This re…
Breaking Down Memory Walls: Adaptive Memory Management in LSM-based Storage Systems (Extended Version)
Chen Luo, Michael J. Carey
Log-Structured Merge-trees (LSM-trees) have been widely used in modern NoSQL systems. Due to their out-of-place update design, LSM-trees have introduced memory walls among the memo…
On Performance Stability in LSM-based Storage Systems (Extended Version)
Chen Luo, Michael J. Carey
The Log-Structured Merge-Tree (LSM-tree) has been widely adopted for use in modern NoSQL systems for its superior write performance. Despite the popularity of LSM-trees, they have…
LSM-based Storage Techniques: A Survey
Chen Luo, Michael J. Carey
Recently, the Log-Structured Merge-tree (LSM-tree) has been widely adopted for use in the storage layer of modern NoSQL systems. Because of this, there have been a large number of…
Efficient Data Ingestion and Query Processing for LSM-Based Storage Systems
Chen Luo, Michael J. Carey
In recent years, the Log Structured Merge (LSM) tree has been widely adopted by NoSQL and NewSQL systems for its superior write performance. Despite its popularity, however, most e…
