Description
The queries select all properties from the tables. The queries should be smart enough to only request the properties outlined in the layer definition. At a minimum request only the geometry and the Feature Id if no properties are selected in the layer. Many tables could be large and contain many large text fields so effectively selecting * from the table can generate large disk I/O and needlessly consume network bandwidth.
