插入实体

Collections 中的实体是指共享同一组字段的数据记录。每条数据记录中的字段值构成一个实体。本页介绍如何在 Collections 中插入实体。

实体概述

在 Milvus 中,实体指的是Collections中共享相同Schema 的数据记录,行中每个字段的数据构成一个实体。因此,同一 Collections 中的实体具有相同的属性(如字段名称、数据类型和其他约束)。

将实体插入 Collections 时,要插入的实体只有包含 Schema 中定义的所有字段才能成功添加。插入的实体将按插入顺序进入名为_default的分区。如果存在某个分区,也可以通过在插入请求中指定分区名称,将实体插入该分区。

Milvus 还支持动态字段,以保持 Collections 的可扩展性。启用动态字段后,你可以在 Collections 中插入 Schema 中未定义的字段。这些字段和值将作为键值对存储在名为$meta 的保留字段中。有关动态字段的更多信息,请参阅动态字段。

将实体插入 Collections

在插入数据之前,需要根据 Schema 将数据组织到字典列表中,每个字典代表一个实体,并包含 Schema 中定义的所有字段。如果 Collections 启用了动态字段,每个字典还可以包含 Schema 中未定义的字段。

本节将向以快速设置方式创建的 Collection 中插入实体。以这种方式创建的 Collection 只有两个字段,分别名为id向量。此外,该 Collections 启用了动态字段,因此示例代码中的 Entities 包含了一个名为 **color ** 的字段,该字段在 Schema 中没有定义。
