Julian Hyde commented on CALCITE-418:
-------------------------------------
Agreed. I made it non-streaming because it was faster to develop. It should
really be streaming. We'll need to decide whether each operator "pushes" or
"pulls".
> Finish implementation of Interpreter

> In OPTIQ-416, we added the Interpreter class. It is able to handle RelNode
> types scan (over array-table at least), filter, project, values, sort; and
> RexNode types literal, inputRef, and calls to < and >.
> This task is to complete implementation of the interpreter. This includes
> implementations of aggregate, join, union, minus, intersect, correlator
> RelNodes and of the set of built-in operators.
> To prove that the interpreter is working, add a test that executes several
> complex queries over small data sets. (Maybe run the foodmart queries
> manually?) Also add a sub-class of SqlOperatorTest that interprets rather
> than generating code.
