Q123.一家公司正在构建一个交互式知识库系统，以帮助其呼叫中心员工更高效地工作.该系统将部署在 AWS 上，每周 7 天. 每天 24 小时不间断使用.该公司以纯文本文件形式存储了 10 多年的客户支持记录.公司需要一个数据库解决方案，公司可以在其中批量加载现有的转录本，并可以在捕获新的转录本时单独加载它们.该解决方案必须提供搜索功能，以识别出现关键字和短语的文字记录.哪种解决方案能够最经济有效地满足这些要求?

正确答案: C. 亚马逊开放搜索服务（Amazon Elasticsearch Service）

解析

To implement this interactive knowledge base system, a database solution was needed to store and search customer support transcripts. The given requirements include bulk loading of transcripts that have already existed for many years, as well as the ability to load new transcripts individually at any time, and providing search capabilities to find keywords and phrases. Considering the best value for money in terms of cost, AWS offers Amazon OpenSearch Service (Amazon Elasticsearch Service), a managed search and analytics engine with high availability, elastic scalability, security, and fault tolerance. Suitable for use in this case.Amazon OpenSearch Service has been optimized for the solution to import data directly into the cluster through a simple API call or a compatible RESTful API. It also offers powerful search engine and analytics capabilities that make it easy to perform text queries and aggregation operations.Therefore, in this case, Amazon OpenSearch Service (Amazon Elasticsearch Service) is the most cost-effective option. Other options such as Amazon Athena and Amazon DynamoDB work for different types of workloads, while Amazon RDS can add cost.为了实现这个交互式知识库系统，需要一种数据库解决方案来存储和搜索客户支持转录。给定的要求包括对已经存在的多年来的转录进行批量加载，以及随时可以单独加载新转录，并提供搜索功能来查找关键字和短语。考虑到成本方面的最佳性价比，AWS提供的Amazon OpenSearch Service (Amazon Elasticsearch Service)，是一个具有高可用性、弹性伸缩性、安全性和容错能力的托管型搜索和分析引擎，适合在此情况下使用。Amazon OpenSearch Service 已经针对解决方案进行了优化，可以通过简单的API调用或兼容的RESTful API直接将数据导入到集群中。它还提供了强大的搜索引擎和分析功能，可以轻松地进行文本查询和聚合操作。因此，在此情况下，Amazon OpenSearch Service (Amazon Elasticsearch Service) 是最具成本效益的选择。其他选项如Amazon Athena和Amazon DynamoDB适用于不同类型的工作负载，而Amazon RDS可能会增加成本。
