DeleteOpenVikingCollection - 删除库

DeleteOpenVikingCollection 用于删除指定的 OpenViking 库。
调用时，通过 ResourceID 指定待删除的库。该值可从创建库接口的响应或库信息页面获取。

说明

注意：
删除前请核对 ResourceID，确认目标库已不再使用，避免影响依赖该库的业务。可先调用 GetOpenVikingCollection，核对库名称及其他信息后再执行删除。

前置条件

已获取火山引擎 AK/SK，用于请求签名。
调用者具备目标 OpenViking 库的删除权限。
已获取待删除库的 ResourceID。
