> LoadRecordFieldRule produces inconsistent query plan
> ----------------------------------------------------
>
> Key: ASTERIXDB-2754
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2754
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: COMP - Compiler
> Affects Versions: 0.9.4
> Reporter: Dmitry Lychagin
> Assignee: Dmitry Lychagin
> Priority: Major
>
> LoadRecordFieldsRule replaces a field access expression with an expression
> this field was assigned to by a record constructor. The problem is that it
> does not clone the replacement expression which makes the query plan
> inconsistent because the same expression is now shared by two operators.
