这种默认行为使索引和浏览数据变得容易-只需开始建立索引文档,Elasticsearch 就会检测布尔值,浮点数和整数值,日期和字符串并将其映射到适当的 Elasticsearch 数据类型。 由于一些原因,在 Elasticsearch 6.0 以后,一个 Index 只能含有一个 type。这其中的原因是:相同 index 的不同映射 type 中具有相同名称的字段是相同;...

Elasticsearch 7.x and later, and all versions of OpenSearch up to 2.15, have a limit of 1,000 shards per node. To adjust the maximum shards per node, configure the cluster.max_shards_per_node setting. From OpenSearch 2.17 and above OpenSearch Service supports 1000 shards for every 16GB of...
