难道做网站的工资都不高吗,如何在百度上营销,客源通app下载,营销品牌推广公司在处理插入milvus数据时，设置了字段长度为512. 明明考虑了预留，插入的数据中没有这么长的，但还是会有报错类似：MilvusException: (code0, messagethe length (564) of 78th string exceeds max length (512) 查找max(len(x) for …

在处理插入milvus数据时，设置了字段长度为512. 明明考虑了预留，插入的数据中没有这么长的，但还是会有报错类似：MilvusException: (code=0, message=the length (564) of 78th string exceeds max length (512)
查找max(len(x) for x in temp_list)之类都没有超过512过，也没超过256过，不知道哪里的数据有问题..
反复截段文本等测试后发现，例如用len(x)看到的字符串长度是10，但保存进milus的长度，并不是..

举例，把数据库长度设为一个小值16：
FieldSchema(name="question", dtype=DataType.VARCHAR, auto_id=False, max_length=16)

再把数据缩到只有一行测试结果插入成功：

line contents is : 你好呀你好 and length is 5
Batches: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████| 1/1 [00:01<00:00, 1.02s/it]
index handle result: Status(code=0, message=)
insert result: (insert count: 1, delete count: 0, upsert count: 0, timestamp: 449735609509740549, success count: 1, err count: 0)

再增加一点文字长度就报错了：

line contents is : 你好呀你好呀 and length is 6
Batches: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████████████████| 1/1 [00:00<00:00, 1.03it/s]
