Near-Data Processing-Enabled and Time-Aware Compaction Optimization for LSM-tree-based Key-Value Stores. 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. david herold facts
