Now let’s create an index named “customer” and then list all the indexes again: PUT /customer?pretty GET /_cat/indices?v 1. 2. 得到(如下)响应: 第一个命令使用PUT动词创建名为"customer"的索引。我们只需在调用的结尾添加pretty,告诉它(如果有可能的话)美化打印JSON响应内容。
Elasticsearch是一个开源的分布式搜索和分析引擎,用于快速、准确地搜索、分析和存储大量数据。它基于Lucene搜索引擎构建,提供了强大的全文搜索、实时分析和可扩展性。 重命名索引是指将现有...
Shards are the pieces of indexes containing actual data. Primary shards are used to hold part of the data stored in an index, while replica shards are copies of primary shards located on different nodes to ensure access to data in the event of a node failure. Elasticsearch automatically migrat...
