--------------------------------------
Summary: child expression for multiple path steps
Key: VXQUERY-156
URL: https://issues.apache.org/jira/browse/VXQUERY-156
Project: VXQuery
Issue Type: Improvement
Reporter: Preston Carman
Currently the child expression takes one path step argument. When multiple
child path expressions are in sequence, the operators materialize each child
result between each operator.
An optimization would be to allow a single child expression to take multiple
arguments. The result would be a single expression that can produce the final
child results without the in between materialized.
Single argument functions: ChildPathStepScalarEvaluator or
ChildPathStepUnnestingEvaluator
