Wisckey: Separating keys from values in ssd-conscious storage
We present WiscKey, a persistent LSM-tree-based key-value store with a performance-
oriented data layout that separates keys from values to minimize I/O amplification. The …

Perseus: A {Fail-Slow} detection framework for cloud storage systems
The newly-emerging''fail-slow''failures plague both software and hardware where the victim
components are still functioning yet with degraded performance. To address this problem …

Redundancy does not imply fault tolerance: Analysis of distributed storage reactions to file-system faults
We analyze how modern distributed storage systems behave in the presence of file-system
faults such as data corruption and read and write errors. We characterize eight popular …

What bugs cause production cloud incidents?
Cloud services have become the backbone of today's computing world. Runtime incidents,
which adversely affect the expected service operations, are extremely costly in terms of user …

If At First You Don't Succeed, Try, Try, Again...? Insights and LLM-informed Tooling for Detecting Retry Bugs in Software Systems
Retry---the re-execution of a task on failure---is a common mechanism to enable resilient
software systems. Yet, despite its commonality and long history, retry remains difficult to …

An empirical study on crash recovery bugs in large-scale distributed systems
In large-scale distributed systems, node crashes are inevitable, and can happen at any time.
As such, distributed systems are usually designed to be resilient to these node crashes via …

Automatic reliability testing for cluster management controllers
Modern cluster managers like Borg, Omega and Kubernetes rely on the state-reconciliation
principle to be highly resilient and extensible. In these systems, all cluster-management …
