UnverifiedIVFFlat uses two parameters, lists (the number of cluster buckets) and probes (the number of buckets actually scanned during a query); lists is often taken as rows/1000 (when the number of rows does not exceed one million) or sqrt(rows), and probes is usually tuned starting from sqrt(lists).70% similarUnverifiedParameter sweeping is a key means of finding the optimal inference configuration (such as batch size, parallelism strategy, memory allocation, etc.).68% similarUnverified列表操作节点可以对数组进行条件筛选、获取前N项或后N项、按升序/降序排序等操作66% similarUnverifiedIVF通过K-Means聚类划分向量空间，查询时只在最近的几个簇内搜索，在亿级以上超大规模数据集的内存效率上更具优势65% similarUnverifiedDegraded queries can be sliced and analyzed along dimensions such as query type, evidence location, and retrieval stage in order to attribute the cause.64% similar
