Managing In-Memory Cubes
In-memory cubes are cached data of business views. They are created by caching pre-computed aggregation functions called measures. Reports and visualizations use the cube data to improve performance.
The generating and updating of in-memory cubes are achieved by scheduling cube tasks. In-memory cubes are similar to scheduled reports that can be run immediately, run once at a specific time or run periodically to select the data from the DBMS and store it in Logi JReport Server. After an in-memory cube is created and ready for use, all web reports, library components, and visual analyses that use the same business view as the in-memory cube will automatically use the cube rather than go to the database for the data. By applying in-memory cubes, your reporting performance will be greatly improved.
The following topics shows how to create, use and manage in-memory cubes as follows:
- Creating In-Memory Cubes
- Viewing and Managing the Cube Tasks
- Recovering and Synchronizing In-Memory Cubes
