SFM: Mitigating Read/Write Amplification Problem of LSM-tree-based Key-value Stores

Hoyoung Lee, Minho Lee, Young Ik Eom
2021 IEEE Access  
Moreover, this approach is not optimized from the perspective of spatial locality since it only considers the skewness among each keyvalue pair.  ...  Consequently, they revealed the detailed characteristics of the realworld workloads, such as spatial locality, temporal locality, and size variation of keys and values.  ...

Key-Value Stores on Flash Storage Devices: A Survey [article]

Krijn Doekemeijer, Animesh Trivedi
2022 arXiv   pre-print
Key-value stores (KV) have become one of the main components of the modern storage and data processing system stack.  ...  This literature survey aims to highlight the changes proposed in the last decade to optimise key-value stores for flash devices and predict what role these devices might play for key-value stores in the  ...  Gilad et al. propose a data structure, known as EvenDB, that combines the batching of LSM-trees with spatial locality [55] .  ...

Holmes

Aidi Pi, Xiaobo Zhou, Chengzhong Xu
2022 Proceedings of the 31st International Symposium on High-Performance Parallel and Distributed Computing  
Experiments with four real-world key-value stores show that compared to a representative CPU isolation approach, Holmes reduces the average (99 th percentile) query latency by up to 49.0% (52.3%) for four  ...  We present Holmes, a user-space approach to SMT interference diagnosis and adaptive CPU scheduling for efficient job co-location in multi-tenant systems.  ...  For example, EvenDB [28] is a recent LSM Tree KV store that is optimized for data with spatial locality.  ...
