Introduction

Compaction is critical to systems that use the Log-structured Merge Tree (LSM-Tree) architecture. High-throughput writes due to the log appending mode and constant data flush from the memory to the disk when data exhausts the memory capacity are causing more and more overlap of data ranges and accumulation of data with the same key. Consequently, they have compromised the reading performance and caused space expansion. Therefore, the compaction mechanism was introduced to optimize reading performance and space problems by continuously recycling old data and merging multiple layers into one with periodic background tasks. However, the compaction policy and task scheduling method have become new problems. The seemingly simple functions require a balance among various resources, including space, I/O, CPU, and cache. …
