Please note that the result is non-deterministic, here is the variation that I'm getting on the exact same test (now it's 3 rows, not 4):
CREATE TABLE t1 (pk INT PRIMARY KEY, i INT, KEY(i)) ENGINE=LevelDB;
|
INSERT INTO t1 VALUES (1,10), (2,20);
|
SELECT i FROM t1 WHERE i NOT IN (8) ORDER BY i DESC;
|

Test case:
CREATE TABLE t1 (pk INT PRIMARY KEY, i INT, KEY(i)) ENGINE=LevelDB;
|
INSERT INTO t1 VALUES (1,10), (2,20);
|
SELECT i FROM t1 WHERE i NOT IN (8) ORDER BY i DESC;
