我有一个s3接收器连接器用于多个主题（topic\u a，topic\u b，topic\u c），topic\u a有字段created\u date，topic\u b，topic\u c有created\u date。我用过下面的 transforms.RenameField.renames 重命名字段（已创建）_date:creation_date)但是，由于只有一个主题创建了日期，而其他主题没有，所以连接器出现故障。
我想将所有消息（来自带有单个连接器的所有主题）移动到带有creation\u date的s3中（如果存在，则将created\u date重命名为creation\u date），但我无法找出regex或transformer来重命名特定主题的字段（如果存在）。
