[Qgis-user] qgis wfs provider loads all features when showing attribute table

[Richard Duivenvoorde]

Hi Martin,

wel att least for the features and attribute tabel this works:

1) make sure you are connecting as WFS 2.x service, WFS 1 did not have 
paging so cannot work with bboxes in the request for big datasets

2) IF you make a connection, with a huge service, make sure you tick the 
"Only request features overlapping the view extent" in the connection 
dialog

3) BEFORE you open the attribute table of the huge service: make sure 
you either choose "Show features visible on map" or ""Show selected 
features" in the option "Attribute table behaviour" in the "Data 
Sources"-tab in General Options.
It is also possible to do this in the attribute table itself (in the 
lower left corner below the table) ... but then you are too late :-) For 
what I know this is a global option, not set per dataset, so you can 
also check it there in another small layer.

If you want to see the exact requests QGIS is firing: use our "QGIS 
Network Logger" plugin, you should see QGIS sending bbox's in the 
request.

Hope this helps

Regards,

Richard Duivenvoorde
