   It is very smart. There are some extra cares need to be taken:
   - There should be only one main record for each id, or it might cross match other records, and get unexpected result
   - To resolve `IN_PARTITIONED_SUBQUERY` (`IN_ID_SET` after resolving `IdSet`), we need to scan all the ids because inverted index won't be applied for `IN_ID_SET`. When there are very few matching ids, this could be slower than sending 2 queries, where the second query is constructed using the ids from first query in an `IN` clause.
   
   Ideally we can build this natively to handle these inefficiencies. The subquery can happen at segment level instead of partition level (`IN_PARTITIONeD_SUBQUERY`) or table level (`IN_SUBQUERY`)
