An Optimization of Key-Value Store Based on Segmented LSM-Tree

WebbLog-Structured Merge Tree (LSM-tree) key-value (KV) stores have been widely deployed in the industry due to its high write efficiency and low costs as a tiered storage. To maintain such advantages, LSM-tree relies on a background compaction operation to merge data records or collect garbages for housekeeping purposes.

Log-structured merge tree (LSM-tree) based key–value stores are widely employed in large-scale storage systems. In compaction, high-level sorted string table files (i.e., SSTables) are merged with low-level overlapping key ranges and sorted for data queries.However, the compaction process incurs write amplification, which degrades …
