PROFILE
Håkon Åmdal
Håkon Aamdal developed a disk-based caching system for the slatedb/slatedb repository, introducing SplitCache as the default mechanism to separate block and metadata caches. Using Rust and asynchronous programming, he centralized and optimized the preload logic to respect startup cache settings, increasing parallelism from 5 to 32 for faster cache warm-up and improved resource utilization. In the following month, Håkon addressed memory spikes during disk cache preload by implementing an efficient prefetching method, reducing peak memory usage and enhancing concurrent file loading. His work demonstrated depth in backend development, caching mechanisms, and performance optimization for large-scale data environments.

Feb 1, 2026February 2026: Delivered a disk-cache system for DbReader in slatedb/slatedb, introducing SplitCache as the default caching layer, increasing startup cache efficiency and data retrieval performance. Implemented centralized preload logic to honor preload_disk_cache_on_startup, and boosted preload parallelism from 5 to 32, resulting in faster startup and lower resource consumption. These changes reduce latency for reads, improve startup behavior, and improve overall resource utilization for large datasets.
