---------------------------------
Summary: Specify region cut size in cubedesc and leave the
RealizationCapacity in model as a hint
Key: KYLIN-1584
URL: https://issues.apache.org/jira/browse/KYLIN-1584
Project: Kylin
Issue Type: Improvement
Reporter: hongbin ma
Assignee: hongbin ma
currently the cube region's size is determined in model's
capacity(RealizationCapacity), it will enforce different realizations under the
same model having uniformed region size. This is not wanted feature because
cube builder might need to try out different region size to tune performance.
I'm suggesting to add a field called "region_size" (float type, 1.0 means 1G
per region) in cube desc to explicitly indicate the cube's region size. The
field "region_size" will not be included in cubedesc's signature calculation.
