[Qgis-developer] Creating large datasets with PyQGIS

[Bo Victor Thomsen]

And you might get your end users to reconsider the decision not to use a 
database solution:

PostgreSQL/PostGIS is free to download and use in any configuration you 
choose, very easy to install compared with other database installation 
procedures and works very well with QGIS.

IMHO, It's the best solution for handling large amounts of GIS vector-data.
