HitShield: Enhanced Swap Eviction Scheme for Multi-Generational LRU

IEEE Access
The least recently used (LRU) algorithm is one of the page replacement algorithms used in the swap mechanism of the Linux kernel. The LRU algorithm has evolved through various modifications and developments, ranging from pseudo LRU to LRU/2, and the ...

SwiftKV: A Metadata Indexing Scheme Integrating LSM-Tree and Learned Index for Distributed KV Stores

Future Internet
Optimizing metadata indexing remains critical for enhancing distributed file system performance. The Traditional Log-Structured Merge-Trees (LSM-Trees) architecture, while effective for write-intensive operations, exhibits significant limitations when ...

面向NVM的IoT时序数据多态协作压缩策略

大数据
压缩策略是影响IoT时序数据存储系统性能的重要因素，而现有压缩策略缺乏针对NVM与IoT时序数据特性的优化机制。因此，提出了面向NVM的IoT时序数据多态协作压缩策略。首先，给出了IoT时序数据的组织结构。然后，针对IoT时序数据在一段时间内较稳定以及在用户态与内核态读写NVM适合的粒度差异较大的情况，设计了分层压缩策略。在用户态接收数据时，采用轻量级的数据压缩算法减少需存储的数据量，也减小了对IoT时序数据的存储效率的影响；针对IoT系统以查询和分析异常时序数据为主的特性，设计了深度压缩算法 ...
