I’m not able to retrieve large amounts of VBD data through a VBD query how can we get the results.
Hi Philip,
I’m not able to retrieve the large amounts of VBD data through a VBD query.
Hi Sudha,
Assign the RTDG node type to two Pega Platform nodes to retrieve the large amounts of VBD data through a VBD query.

In the Planner settings section, configure the Visual Business Director (VBD) planner:
-
In the Poll interval (seconds) field, enter the frequency for querying the server for new data.
The default frequency is 10 seconds.
-
Optional: To edit the maximum number of 3D objects that the VBD planner draws on the main scene, in the Maximum objects at current dimension levels field, enter an integer value.
The total number of 3D objects is calculated by multiplying the number of values on the y-axis by the number of values on the x-axis. For example, if the scene has 16 values at Group level (y-axis) and 4 values at Direction level (x-axis), the total number of 3D objects is 64.
