The state of the art of metadata managements in large-scale distributed file systems—scalability, performance and availability
File system metadata is the data in charge of maintaining namespace, permission semantics
and location of file data blocks. Operations on the metadata can account for up to 80% of …

PACTree: A high performance persistent range index using PAC guidelines
Non-Volatile Memory (NVM), which provides relatively fast and byte-addressable
persistence, is now commercially available. However, we cannot equate a real NVM with a …

Nap: A {Black-Box} Approach to {NUMA-Aware} Persistent Memory Indexes
We present Nap, a black-box approach that converts concurrent persistent memory (PM)
indexes into NUMA-aware counterparts. Based on the observation that real-world workloads …

Differentiated {Key-Value} storage management for balanced {I/O} performance
Modern key-value (KV) stores adopt the LSM-tree as the core data structure for managing
KV pairs, but suffer from high write and read amplifications. Existing LSM-tree optimizations …
