Query federation improves performance by pushing predicate conditions down to the remote data source for filtering before returning results, but its performance ceiling is constrained by the throughput capacity of the remote system and network latency, which may become a bottleneck in large-scale full-table scan or high-frequency query scenarios.

UnverifiedFor large-scale datasets, cascading filters can reduce backend query pressure because each filter only needs to run on the subset of results from the previous level rather than performing a full table scan.74% similarUnverifiedDetails such as the performance and cost impact of real-time queries on the underlying dataset, the latency of executing security policies per reader under high concurrency, and the complexity boundaries of building applications with natural language remain to be verified through actual use.73% similarUnverified从事件监听打断点并沿调用栈逐层追溯，比盲目全局搜索效率更高且不易遗漏中间数据转换环节73% similarUnverifiedMulti-hop queries need to traverse multiple information nodes in a step-by-step manner, and vector retrieval is ill-suited for such scenarios due to its lack of a relational dimension.71% similarUnverifiedEven merely routing requests containing regulated data to a non-compliant region to complete inference before returning the results may constitute a compliance risk.70% similar
