/*
* Description : Equi joins two datasets, FacebookUsers and FacebookMessages, based on their user's id.
* We first expect FacebookUsers' primary index to be used
* to satisfy the range condition on it's primary key.
* FacebookMessages has a secondary btree index on author-id-copy, and given the 'indexnl' hint
* we expect the join to be transformed into an indexed nested-loop join.
* Success : Yes
