      Description

      --source include/have_partition.inc
       
      INSTALL SONAME 'ha_connect';
       
      CREATE TABLE t1 (
        id INT,
        f VARCHAR(32),
        PRIMARY KEY (id DESC)
      ) ENGINE=CONNECT TABLE_TYPE=DOS FILE_NAME='f.txt';
       
      INSERT INTO t1 VALUES(1,'one'),(2,'two'),(3,'three');
       
      SELECT * FROM t1 WHERE id >= 2;
       
      # Cleanup
      DROP TABLE t1;
      UNINSTALL SONAME 'ha_connect';
      

      The SELECT returns an empty result set

      preview-10.8-MDEV-13756-desc-indexes c10e10c6

      SELECT * FROM t1 WHERE id >= 2;
      id	f
      DROP TABLE t1;
      

      With an ascending key it returns two rows as expected:

      SELECT * FROM t1 WHERE id >= 2;
      id	f
      2	two
      3	three
      DROP TABLE t1;
