FAST '24 - Symbiosis: The Art of Application and Kernel Cache Cooperation

Yifan Dai, Jing Liu, Andrea Arpaci-Dusseau, and Remzi Arpaci-Dusseau, University of Wisconsin—Madison

We introduce Symbiosis, a framework for key-value storage systems that dynamically configures application and kernel cache sizes to improve performance. We integrate Symbiosis into three production systems — LevelDB, WiredTiger, and RocksDB — and, through a series of experiments on various read-heavy workloads and environments, show that Symbiosis improves performance by 1.5× on average and over …
