理想情况下，用户使用insert自己输入的id应该自己保证id为unique，如果不是unique，milvus也不会帮你去重(去重的功能也许在3.0的某个版本中支持)。所以，insert多条相同id的数据，显示的数据行数会增加。 如果用的upsert，相当于insert+delete操作，会把旧的该条id数据删除，再insert该条id的新数据。所以，显示的数据行数不会增加。 |

发现insert同一个id多次，collection中Entity数量会跟着增加，但是根据id查询，结果只有一条；但是upsert同一个id多次，Entity数量不会增加。
insert 同一个id多次，id查询会覆盖吗？
