Diff view types have diff max views in results.
The view config should tell you the max when you enter a number above the max.
If you are referring to number of view configs on a dashboard, you need to consider each view generates 1+ RIB call to the DA/vertica.
There are only 40 shared threads in PC to run RIB calls. So if you have a dashboard for like 30 view configs, that means it will use 30 of those 40 threads. So they will need to compete with other dashboards for those 40 threads. And how fast those 40 run depend on speed of vertica to complete the SQL calls.
Just something to think about making very large dashboards.
