/*
 * Description    : Self-equi joins on a dataset using two fields - countA and countB.
 *                  TweetMessages has a secondary btree index on countB, and given the 'indexnl' hint
 *                  we expect the join to be transformed into an indexed nested-loop join.
 * Success        : Yes
