WiscKey: separating keys from values in SSD-conscious storage

TL;DR: WiscKey as discussed by the authors is a persistent LSM-tree-based key-value store with a performance-oriented data layout that separates keys from values to minimize the I/O amplification.
Proceedings ArticleDOI

Optimistic crash consistency

TL;DR: It is demonstrated how to build an optimistic commit protocol that correctly recovers from crashes and delivers high performance, and two new file-system primitives, osync() and dsync(), that decouple ordering of writes from their durability are introduced.
Journal ArticleDOI

WiscKey: Separating Keys from Values in SSD-Conscious Storage

TL;DR: WiscKey is a persistent LSM-tree-based key-value store with a performance-oriented data layout that separates keys from values to minimize I/O amplification and is faster than both LevelDB and RocksDB in all six YCSB workloads.
Proceedings ArticleDOI

All file systems are not created equal: on the complexity of crafting crash-consistent applications

TL;DR: It is found that applications use complex update protocols to persist state, and that the correctness of these protocols is highly dependent on subtle behaviors of the underlying file system, which is referred to as persistence properties.
