Summary: Add tile and measure elements to lattice model element
Key: OPTIQ-406
URL: https://issues.apache.org/jira/browse/OPTIQ-406
Project: Optiq
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Add tile and measure elements to the lattice model element. This will allow the
model author to define tiles (materialized aggregates) as part of the lattice
definition.
Each tile has a list of dimensions (each of which is a column of the lattice)
and a list of measures (each of which is an aggregate function applied to zero
or more arguments, each of which is a column of the lattice).
The lattice has a default list of measures; this is used by any tiles that do
not specify a measure list explicitly.
