> for the following table:
> {code:borderStyle=solid}
> CREATE TABLE ORDERBY_TEST (
> ORGANIZATION_ID INTEGER NOT NULL,
> CONTAINER_ID INTEGER NOT NULL,
> SCORE INTEGER NOT NULL,
> ENTITY_ID INTEGER NOT NULL,
> CONSTRAINT TEST_PK PRIMARY KEY (
> ORGANIZATION_ID,
> CONTAINER_ID,
> SCORE,
> ENTITY_ID
> ));
> {code}
>
> If we execute explain on the following sql:
> {code:borderStyle=solid}
> SELECT ORGANIZATION_ID,SCORE FROM ORDERBY_TEST GROUP BY ORGANIZATION_ID,
> SCORE ORDER BY ORGANIZATION_ID DESC, SCORE DESC
> {code}
> the result is :
> {code:borderStyle=solid}

> | PLAN |
> +----------------------------------------------------------------------+
> | CLIENT 1-CHUNK PARALLEL 1-WAY FULL SCAN OVER ORDERBY_TEST |
> | SERVER FILTER BY FIRST KEY ONLY |
> | SERVER AGGREGATE INTO DISTINCT ROWS BY [ORGANIZATION_ID, SCORE] |
> | CLIENT MERGE SORT |
> | CLIENT SORTED BY [ORGANIZATION_ID DESC, SCORE DESC] |
> +----------------------------------------------------------------------+
> {code}
> from the above explain result, we can see that the ORDER BY ORGANIZATION_ID
> DESC, SCORE DESC is not compiled out,but obviously it should be compiled out
> as OrderBy.REV_ROW_KEY_ORDER_BY.
