This is probably the approach I will follow, but what if I want my
container objects notified? Even if I don't it seems the default
Folder implementation follows this logic and so if you have a folder
with several large images for example, then you will pay a price
whenever an event is issued. In general it seems that any change
will result in the entire ZODB being read for each event
dispatch...if I still follow the logic here.
You're probably talking about dispatchToSublocations. This is the
code that looks up a containers sublocations and dispatches the
event to them.
One way to prevent this behaviour for your container is to write a
new ISublocations adapter for your container that simply returns an
def __init__(self, context):
self.context = context
