Engine Optimization Demo
This sample demonstrates virtual-mode and without-counter-mode
optimization.
Features:
Based on the schema specified, the engine determines whether
specific optimizations may be applied.
If records are not sorted for a flat table, then the Virtual
mode is applied.
Records do not have to be touched (except when
drawing).

Interactive Features:
- You will be able to see the automatic switching between the
virtual mode and without-counter mode when you select the "Flat
List VirtualMode" example.
- The engine will be initialized using the virtual mode.
- Once you
sort by a column, the virtual mode will be turned off, but the
without-counter mode will still continue to work.
- Once you sort by a
column, the counters will then be enabled.
