Elasticsearch 不仅在各种与搜索相关的任务中表现优于 OpenSearch,而且还被证明具有更高的资源效率。默认情况下,OpenSearch 对数据流使用best_speed编解码器(优先考虑查询速度而不是存储效率),而 Elasticsearch 使用best_compression。使用默认的开箱即用设置,Elasticsearch 使用的磁盘空间减少了 37%,并且当两者都使用best_co...
在此测试中,Elasticsearch 始终比 OpenSearch 开箱即用的速度快,只有在两种情况下 OpenSearch 更快,而且快不了多少(knn-10-100 和 knn-100-1000)。涉及 knn-10-50、knn-10-100 和 knn-100-1000 与过滤器结合的任务显示出高达 7 倍的差异(112ms vs 803ms)。

Elasticsearch 的开箱即用的向量搜索速度比 OpenSearch 快 2 到 12 倍。 向量搜索正在彻底改变我们进行相似性搜索的方式,尤其是在人工智能和机器学习等领域。随着向量嵌入模型的日益普及,高效搜索数百万个高维向量的能力变得至关重要。 Elastic 收到了来自社区的大量请求,要求我们澄清 Elasticsearch 和 OpenSearch 之间的...
1. 什么是 Elasticsearch? Elasticsearch 是一个基于 Apache Lucene 构建的开源、RESTful、分布式搜索和分析引擎。它旨在处理大量数据,使其成为日志和事件数据管理的流行选择。 Elasticsearch 还以其实时功能而闻名,允许用户在数据模式发生时探索、分析和可视化。 除了日志和事件数据管理之外,Elasticsearch 还常用于全文搜索和...
This is a surefire way of deprecating the performance of your Elasticsearch cluster very quickly, and if that’s why you selected Elasticsearch in the first place, that doesn’t make much sense. Do you want to make your Elasticsearch queries run ...
But how do you know if your new OpenSearch performs as well and functions as correctly as the existing Elasticsearch? Even when comparing old with new versions, upgrades don’t always translate into better performance. If your cluster is important, you’ll probably run both search engines in ...
OpenSearch as well as 7.xversions of Elasticsearch have a default setting of no more than 1,000 shards per node. OpenSearch/Elasticsearch throw an error if a request, such as creating a new index, would cause you to exceed this limit. If you encounter this error, you have several options...
OpenSearch vs Elasticsearch PerformanceThe OpenSearch project was forked from the last ElasticSearch release under the Apache 2.0 license and is almost the same in functionality. The API is completely the same.Below, we are sharing the results of a performance test on two Magento environments with ...
