> Key: ASTERIXDB-2434
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2434
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Reporter: Dmitry Lychagin
> Assignee: Dmitry Lychagin
> Priority: Minor
>
> 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.
> We invoke SetExecutionModeRule during logical rewrites, but by the time
> EnforceStructuralPropertiesRule is invoked there might be new operators in
> the plan. We need to invoke SetExecutionModeRule right before
> EnforceStructuralPropertiesRule to guarantee that execution mode is properly
> set for all operators.
