+/**
+ * Pushes field-access expression to the external dataset scan to minimize the size of the record.
+ * This rule currently does not remove the field access expression in ASSIGN and SCAN operators. Instead,
+ * it adds the requested field names to external dataset details to produce records that only contain the requested
+ * fields. Thus, no changes would occur in the plan's structure after firing this rule.
+ * Example:
+ * Before plan:
+ * ...
+ * select (and(gt($$00, 20), gt($$r.getField("salary"), 70000)))
+ * ...
+ * assign [$$00] <- [$$r.getField("personalInfo").getField("age")]
+ * ...
+ * data-scan []<-[$$r] <- ParquetDataverse.ParquetDataset
+ * <p>
+ * After plan:
+ * ...
+ * select (and(gt($$00, 20), gt($$r.getField("salary"), 70000)))
+ * ...
+ * assign [$$00] <- [$$r.getField("personalInfo").getField("age")]
+ * ...
+ * data-scan []<-[$$r] <- ParquetDataverse.ParquetDataset project (personalInfo.age, salary)
+ * <p>
+ * The resulting record $$r will be {"personalInfo":{"age": *AGE*}, "salary": *SALARY*}
+ * and other fields will not be included in $$r.
