This task seems to be common for any database application of a significant size.
XAF doesn't provide special solutions for this task. I suggest that you consider standard approaches that can be applied to common Windows Forms or ASP.NET applications. For example:
- Need advice on archiving large SQL Server tables
- Database design: one huge table or separate tables?
- How to manage a huge database?.
You can find more solutions at google.com.
Currently, XPO provides the XPServerCollectionSource class to reduce the amount of loaded information when there is a huge number of records to be loaded. In XAF, the IModelOptions.UseServerMode property in the Application Model switches core XAF methods to create this object instead of the XPCollection object in some scenarios.
Feel free to contact us if you have difficulties integrating some standard solution.
