Graph indexes for billion-scale vector collections can exceed a single server's DRAM capacity. Passive RDMA-based disaggregated memory provides scalable capacity without memory-node computation, but conventional best-first search performs poorly in this setting. Fine-grained and unnecessary remote reads increase commun...

Log-structured merge-tree-basedkey-value stores(LSM-KVSs) expose hundreds of configuration knobs to support diverse deployments. Navigating this configuration space remains difficult because good settings depend on workload behavior, hardware limits, resource budgets, and LSM-KVS internal state. Recent LLM-based tuners...
