[Erp5-dev] visited objects and selection

[bartek]

Hello

I'd like to record information about the fact that a user "visited" a 
certain object (means he opened a web page publishing this object). The 
purpose is to be able to display a list of objects and mark the ones he 
hasn't seen yet.

The solution I consider is storing the info in a dedicated per-user 
selection, and then retrieving it for every object in a list. The 
question is, would that be an eficient solution? I'd soon end up storing 
hundreds of object identifiers per every user, wouldn't it hurt 
performance? And if so, what other solution may be considered?
