Will Wilson on "Swarm Testing"
Main: Will Wilson on "Swarm Testing"
Abstract: Swarm testing is a novel and inexpensive way to improve the diversity of test cases generated during random testing. Increased diversity leads to improved coverage and fault detection...Experimental results show that swarm testing increases coverage and can improve fault detection dramatically; for example, in a week of testing it found 42% more distinct ways to crash a collection of C compilers than did the heavily hand-tuned default configuration of a random tester.
Bio: Will Wilson is the CEO and co-founder of Antithesis, purveyors of the finest testing platform in the land. Before Antithesis, Will was an early engineer at FoundationDB and worked on Google Cloud Spanner.
Mini: Almog Gavra on "Dostoevsky: Better Space-Time Trade-Offs for LSM-Tree Based Key-Value Stores via Adaptive Removal of Superfluous Merging"
Abstract: We show that all mainstream LSM-tree based key-value stores in the literature and in industry suboptimally trade between the I/O cost of updates on one hand and the I/O cost of lookups and storage space on the other…We put everything together to design Dostoevsky, a key-value store that adaptively removes superfluous merging by navigating the Fluid LSM-tree design space based on the application workload and hardware. We implemented Dostoevsky on top of RocksDB, and we show that it strictly dominates state-of-the-art designs in terms of performance and storage space.
Bio: Almog is a co-founder at responsive.dev and a SlateDB committer, working on the most ambitious database project in history. He writes about how storage systems work on bitsxpages.com and occasionally draws an XKCD inspired comic with a snarky take on databases.
