Hey Shon,

That's brave!  Some entry points to get you started.

- *CubeManager *& *CubeDescManager *manages cube metadata which drives
everything
- *CubingJobBuilder *creates a chain of steps to build a cube, look into
each step from there
- Kylin uses Calcite <http://calcite.incubator.apache.org/> for SQL parsing
and execution, entrance is *OLAPSchema*
- SQL needs data to fulfill, *CubeStorageEngine *is entrance of storage
layer

Good luck~
