> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Reporter: Vijay Sarathy
> Priority: Major
>
> For an indexnl plan, we currrently do not show card/cost in the explain
> output. These annotations are added at the end of join enumeration on the
> logical operators in EnumerateJoinsRule. For indexnl join, there are no
> corresponding physical operators (as the data scan gets converted into
> unnest_map), so these cards are not accessible in the final
> EstimatedCostComputationVisitor code.
