thats a bit of a "how long is a piece of string" question really. I would say that it may or may not be a problem ;) For really large volumes of data, people normally may filter it if they have some basic criteria they can use, and the data comes from a database etc. Relational databases are good as fishing for data from a large set, they are designed for that specifically. Havign said that, the "from" keyword in 3.1will certainly help with that, as you can have a query embedded that pulls data from a datasource only when needed.
