Title: BI: Major Rework of Code. Apache processes now share computated data
Component: BI
Level: 2
Class: New Feature
Version: 1.4.0i3
Previously, each apache process had to compile the all BI aggregation trees by itself.
This generated lots of CPU load during core restart, especially on larger BI
configurations.
With this update, an apache process no longer computes the BI trees only for personal
usage.
The computation results are now shared between the different processes through cache
files.
If you encounter any bugs with this new mechanism you can switch back to the old
implementation via the global settings option <i>Use legacy compilation for BI
aggregations (slower)</i>.
