新的连接索引技术显著加快搜索引擎查询速度

研究人员开发了一种在搜索引擎中执行连接的新方法,特别是在 Apache Solr 上使用 Lucene 段。该技术改编自关系数据库系统,创建了一个连接索引,通过避免查询时键转换并启用并行、剪枝的半连接来显著提高性能。基准测试显示,与现有的 Solr 连接实现相比,平均查询延迟降低了 5.4 倍,并且在更高的负载和并发下性能增益会增加。 AI

影响 提高了搜索引擎中数据检索的效率,可能影响依赖于大规模数据索引和查询的 AI 应用。

    为搜索引擎构建索引:可裁剪的 Lucene 分段并行半连接

    Joins are second-class citizens in search engines: existing query-time join implementations in Lucene are limited either in performance or in capability, forcing a choice between fast joins scoped to a single index and slower joins that span independently managed indices. We carr…
