+ * Factors out common sub-expressions by assigning them to a variables, and replacing the common sub-expressions with references to those variables.
+ *
+ * Preconditions/Assumptions:
+ * Assumes no projects are in the plan. This rule ignores variable reference expressions and constants (other rules deal with those separately).
+ * 
+ * Postconditions/Examples:
+ * Plan with extracted sub-expressions. Generates one assign operator per extracted expression.
+ * 
+ * Example 1 - Simple Arithmetic Example (simplified)
+ * 
+ * Before plan:
+ * assign [$$1] <- [5 + 6 - 10]
+ *   assign [$$0] <- [5 + 6 + 30]
+ * 
+ * After plan:
+ * assign [$$1] <- [$$5 - 10]
+ *   assign [$$0] <- [$$5 + 30]
+ *     assign [$$5] <- [5 + 6]
+ * 
+ * Example 2 - Cleaning up 'Distinct By' (simplified)
+ * 
+ * Before plan: (notice how $$0 is not live after the distinct)
+ * assign [$$3] <- [field-access($$0, 1)]
+ *   distinct ([%0->$$5])
+ *     assign [$$5] <- [field-access($$0, 1)]
+ *       unnest $$0 <- [scan-dataset]
+ * 
+ * After plan: (notice how the issue of $$0 is fixed)
+ * assign [$$3] <- [$$5]
+ *   distinct ([$$5])
+ *     assign [$$5] <- [field-access($$0, 1)]
+ *       unnest $$0 <- [scan-dataset]
+ * 
+ * Example 3 - Pulling Common Expressions Above Joins (simplified)
+ * 
+ * Before plan:
+ * assign [$$9] <- funcZ(funcY($$8))
+ *   join (funcX(funcY($$8)))
+ * 
+ * After plan:
+ * assign [$$9] <- funcZ($$10))
+ *   select (funcX($$10))
+ *     assign [$$10] <- [funcY($$8)]
+ *       join (TRUE)

+/**
+ * Replaces variable reference expressions with their assigned function-call expression where applicable
+ * (some variables are generated by datasources).
+ * Inlining variables may enable other optimizations by allowing selects and assigns to be moved
+ * (e.g., a select may be pushed into a join to enable an efficient physical join operator).
+ * 
+ * Preconditions/Assumptions:
+ * Assumes no projects are in the plan. Only inlines variables whose assigned expression is a function call 
+ * (i.e., this rule ignores right-hand side constants and other variable references expressions  
+ * 
+ * Postconditions/Examples:
+ * All qualifying variables have been inlined.
+ * 
+ * Example (simplified):
+ * 
+ * Before plan:
+ * select <- [$$1 < $$2 + $$0]
+ *   assign [$$2] <- [funcZ() + $$0]
+ *     assign [$$0, $$1] <- [funcX(), funcY()]
+ * 
+ * After plan:
+ * select <- [funcY() < funcZ() + funcX() + funcX()]
+ *   assign [$$2] <- [funcZ() + funcX()]
+ *     assign [$$0, $$1] <- [funcX(), funcY()]

+/**
+ * The lateral view join operator is used for FROM src LATERAL VIEW udtf()...
+ * This operator was implemented with the following operator DAG in mind.
+ * For a query such as
+ * SELECT pageid, adid.* FROM example_table LATERAL VIEW explode(adid_list) AS
+ * adid
+ * The top of the operator DAG will look similar to
+ * [Table Scan] | [Lateral View Forward] / \ [Select](*) [Select](adid_list) | |
+ * | [UDTF] (explode) \ / [Lateral View Join] | | [Select] (pageid, adid.*) |
+ * ....
+ * Rows from the table scan operator are first to a lateral view forward
+ * operator that just forwards the row and marks the start of a LV. The select
+ * operator on the left picks all the columns while the select operator on the
+ * right picks only the columns needed by the UDTF.
+ * The output of select in the left branch and output of the UDTF in the right
+ * branch are then sent to the lateral view join (LVJ). In most cases, the UDTF
+ * will generate > 1 row for every row received from the TS, while the left
+ * select operator will generate only one. For each row output from the TS, the
+ * LVJ outputs all possible rows that can be created by joining the row from the
+ * left select and one of the rows output from the UDTF.
+ * Additional lateral views can be supported by adding a similar DAG after the
+ * previous LVJ operator.

+     * Compares the records already known by the client for the given job's result set id with the records that the
+     * dataset directory service knows and if there are any newly discovered records returns a whole array with the
+     * new records filled in.
+     * This method has a very convoluted logic. Here is the explanation of how it works.
+     * If the ordering constraint has to be enforced, the method obtains the first null record in the known records in
+     * the order of the partitions. It always traverses the array in the first to last order!
+     * If known records array or the first element in that array is null in the but the record for that partition now
+     * known to the directory service, the method fills in that record in the array and returns the array back.
+     * However, if the first known null record is not a first element in the array, by induction, all the previous
+     * known records should be known already be known to client and none of the records for the partitions ahead is
+     * known by the client yet. So, we check if the client has reached the end of stream for the partition corresponding
+     * to the record before the first known null record, i.e. the last known non-null record. If not, we just return
+     * null because we cannot expose any new locations until the client reaches end of stream for the last known record.
+     * If the client has reached the end of stream record for the last known non-null record, we check if the next record
+     * is discovered by the dataset directory service and if so, we fill it in the records array and return it back or
+     * send null otherwise.
+     * If the ordering is not required, we are free to return any newly discovered records back, so we just check if
+     * arrays are equal and if they are not we send the entire new updated array.
+     * 
+     * @param jobId
+     *            - Id of the job for which the directory records should be retrieved.
+     * @param rsId
+     *            - Id of the result set for which the directory records should be retrieved.
+     * @param knownRecords
+     *            - An array of directory records that the client is already aware of.
+     * @return
+     *         - Returns null if there aren't any newly discovered partitions enforcing the ordering constraint
+     * @throws HyracksDataException
+     *             TODO(madhusudancs): Think about caching (and still be stateless) instead of this ugly O(n) iterations for
+     *             every check. This already looks very expensive.
