Question:
OBI
already has a caching mechanism in presentation layer and BI server
layer. How is the new in-memory caching better for performance?
Answer:
OBI Caching only speeds up what has been seen before. An In-memory
data structure generated by the summary advisor is optimized to provide
maximum value by accounting for the expected broad usage and drilldowns.
It is possible to adapt the in-memory data to seasonality by running
the summary advisor on specific workloads. Moreover, the in-memory data
is created in an analytic database providing maximum performance for the
large amount of memory available.
