> This may be related to PHOENIX-3451 but the behavior is different so filing it separately.
> Steps to repro:
> CREATE TABLE IF NOT EXISTS TEST.TEST (
>     ORGANIZATION_ID CHAR(15) NOT NULL,
>     CONTAINER_ID CHAR(15) NOT NULL,
>     ENTITY_ID CHAR(15) NOT NULL,
>     SCORE DOUBLE,
>     CONSTRAINT TEST_PK PRIMARY KEY (
>         ORGANIZATION_ID,
>         CONTAINER_ID,
>         ENTITY_ID
>     )
> ) VERSIONS=1, MULTI_TENANT=TRUE, REPLICATION_SCOPE=1, TTL=31536000;
> CREATE INDEX IF NOT EXISTS TEST_SCORE ON TEST.TEST (CONTAINER_ID, SCORE DESC, ENTITY_ID
DESC);
> UPSERT INTO test.test VALUES ('org1','container1','entityId6',1.1);
> UPSERT INTO test.test VALUES ('org1','container1','entityId5',1.2);
> UPSERT INTO test.test VALUES ('org1','container1','entityId4',1.3);
> UPSERT INTO test.test VALUES ('org1','container1','entityId3',1.4);
> UPSERT INTO test.test VALUES ('org1','container1','entityId2',1.5);
> UPSERT INTO test.test VALUES ('org1','container1','entityId1',1.6);
> SELECT DISTINCT entity_id, score
> FROM test.test
> WHERE organization_id = 'org1'
> AND container_id = 'container1'
> ORDER BY score DESC
> Notice that the returned results are not returned in descending score order. Instead
they are returned in descending entity_id order. If I remove the DISTINCT or remove the secondary
index the result is correct.
