HydraList: A Scalable In-Memory Index Using Asynchronous Updates and Partial Replication
Summary: HydraList is a scalable, in-memory index for massive multi-core machines using asynchronous updates and partial replication. It splits into search and data layers; replicating the search layer across NUMA nodes reduces synchronization and cache misses, boosting performance across diverse workloads.
