Dmitry Lychagin updated ASTERIXDB-2434:
---------------------------------------
Description:
Computation of required child properties for UnionAll depends on the execution
mode of its children
(OperatorPropertiesUtil.checkUnpartitionedAndGetPropertiesVector()). Therefore
it's important to have correct execution mode for its input operators at that
time.
InjectTypeCastForUnionRule and IntroduceDynamicTypeCastRule currently create
new Assign operators, but do not set their execution mode. They should copy
execution mode from their inputs
was:
Computation of required child properties for some operators (UnionAll, for
example) depends on the execution mode of its children
(OperatorPropertiesUtil.checkUnpartitionedAndGetPropertiesVector()). Therefore
it's important to have correct execution mode for all operators at that time.
InjectTypeCastForUnionRule and IntroduceDynamicTypeCastRule need to set
execution mode for new Assign operators they're creating
> Ensure operator execution mode before invoking EnforceStructuralPropertiesRule
