Data Streaming is a feature of spatial database connections that allows data to be dynamically queried to the view. As you pan or zoom in and out, the view will be automatically updated with queried data. This allows you to work uninterrupted with the OpenCities Map tools by eliminating the need to re-query as your view extents change.
Named Connections
In named connections, Data Streaming can be set to true or false for each category. Doing so will set it for all features that belong to that category. If desired, you can expand the category and set data streaming to True or False for individual features.
For projects without defined categories to organize your features, the Data Streaming option is applied to the connection name or to individual features as shown.
Ad Hoc Connections
For ad hoc connections, data streaming can be set to true or false for the Current Session or for each individual feature.
