RocksDB based on LSM-Tree is widely used in Facebook. This work aims to model and analysis RocksDB workloads at Facebook.
This work points out that how to utilize low-level performance of a hierarchical storage system.
This work focuses on the bottleneck of file-mapping in NVM filesystems.
Intro With the development of storage device, lots of novel stuff come to world, including NAND SSD, Optane 3D XPoint, STT-RAM… Personal machines have already multi-level storage: SRAM on CPU L2/L2 cache, DRAM on CPU’s DIMMs, SSD to accelerate operating system, and HDD to storage big file like media, movie.
Hey there, due to well known issues and less-well known issues, this public blog would forever remove anything about illegal and personal contents! Hope you guys can still enjoy the fun of tech, aka the general computer science :)
Paper notes about Assise, a distributed FS on NVM. Assise keeps data & metadata in clients (opposite to disaggregation) to enble fast recovery and high perf.
paper notes about XStore from SJTU, which uses learned cache (aka learned index) for distributed DRAM KVS.
paper notes about Persimmon from UCB & MSR uses state machine scheme to utilize PM to add persistence to in-mem storage systems
