有没有办法使用 java 高级客户端在 ElasticSearch 中删除/更新现有别名？

Question

有没有办法使用 Java 高级休息客户端删除/更新现有别名（不是索引，只是别名）？

Answer 1

I do not know what version of Elasticsearch you are using but I found something like that: https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-update-aliases.html

Example:

IndicesAliasesRequest request = new IndicesAliasesRequest();
AliasActions removeAction =
    new AliasActions(AliasActions.Type.REMOVE)
    .index("index3")
    .alias("alias3");
request.addAliasAction(removeAction);

Answer 2

从 ES 7.6 开始，您可以执行以下操作：

DeleteAliasRequest request = new DeleteAliasRequest("index1", "alias1");
