WebbAbstract. 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 … Webb11 nov. 2016 · PCP uses a pipelined compaction procedure to fully utilize both CPUs and I/O devices, in order to speeding up the compaction procedure. All this research focuses on decreasing the compaction frequency, accelerating the speed of compaction or confining compactions on hot data key-ranges. share apps windows 10 users
