Hi, When a child watcher is fired, it can happen that when the children are read, a deleted node is already added back. So, from the list of children, it's as if nothing has changed. However, it could be important for an app to know in this case that something has changed. I could include some metadata per node and read every child node each. However, reading the data for every child could be expensive. What's best way to handle this case?
Thanks, Jun
