DeleteMultipleObjects接口用于删除同一个存储空间(Bucket)中的多个文件(Object)。 注意事项 单次调用DeleteMultipleObjects接口最多允许删除1000个文件。 如果Bucket创建了数据复制规则,且数据复制策略配置为增/删/改 同步,则调用DeleteMultipleObjects删除该Bucket内的Object时,数据复制策略关联的目标Bucket也会删除对应的Obje...

Deleting a row from a nickname deletes the row from the data source object to which the nickname refers. Deleting a row from a view deletes the row from the table on which the view is based if no INSTEAD OF trigger is defined for the delete operation on this view. If such a trigger...

下面的示例将删除远程表中的行。 该示例从使用sp_addlinkedserver创建指向远程数据源的链接开始。 然后,将链接服务器名称MyLinkServer指定为 server.catalog.schema.object 形式的由四个部分组成的对象名称的一部分。 SQL USEmaster; GO-- Create a link to the remote data source.-- Specify a valid server nam...
如上图所示,在milvus中,delete和insert一样,同样要双写存储和计算节点。在DataNode上,delete操作被存储为deltalogs然后upload到object storage上, 在QueryNode上,delete被delegator转发给所有“可能包含对应delete数据”的segment,在对应计算节点上生成对应的delete mask以供查询,从而保证delete的可见性。
