CmptQuiet: Optimizing Tail Latency and Throughput in LSM-Tree Key-Value Stores via Contention-Aware Compaction

Log-Structured Merge-Tree (LSM-tree) based Key-Value stores are foundational to data center storage but suffer from high tail latency due to a fundamental read-write trade-off and disruptive compaction. This paper introduces CmptQuiet, a system that breaks this trade-off to deliver low tail latency without sacrificing...
