RE: what is burst reporting

In normal circumstances, report users would run reports with their seclection of prompt values and view the output. In a scenario, when the number of users is high and the possible combinations of prompt values that they would query for is even higher, it is a good idea to pre-process reports for them and provide a user with all possible outputs that he/she would generally view / har the rights to view. This pre-processing or pre-generation can be done through the process called "Bursting".
The reports are "burst" in advance and all possible output combinations are generated and published on the webserver for users to view. Its a common practice to save burst outputs in *.pdf format, although other outputs can also be saved.
The advantage is obvious. It saves report generation time at runtime (sometimes into several minutes) and helps balance processing load on the reportnet server.
However, this option should only be exercised when the processing volumes are higher than normal, else it would just be an overkill. This may be not be a good option in near-real-time data warehouse implementations. |
