Description Lin Zhu CLA 2007-05-02 03:03:07 EDT 
Currently the Cube is always created in disk. However we might need it to be created in memory instead. This would enhance the performance in case that cube is relatively small.

Comment 2 Lin Zhu CLA 2007-08-21 23:32:25 EDT 
Add new appContext property DataEngine.IN_MEMORY_CUBE_SIZE which takes an integer (N) as value. Data engine will then use up to N MB physical memory for materializing a single cube. If all those N MB physical memory is consumed then we will use disk to save cube data.

The DtE side fixing has been done. Reassign to GUI for their part fixing.

Added option in preference page, reassign to viewer to pass setting to data engine..
Comment 4 Jerry Cheng CLA 2007-08-22 23:57:24 EDT 
Add new option in web.xml and URL to allow user to specify the memory size for creating cube.
Also add a new group in configuration page of wtp plugin.
