Abstract
Techniques are described herein for efficient set operation execution. According to some embodiments, a request is received to perform a set operation with respect to a first data set and a second data set. The request may identify the first data set, the second data set, and a type of set operation to perform. In response to receiving the request, a hash table is generated in memory from a first set of records in the first data set, and a second set of records from the second data set is probed against the hash table. Based on probing the hash table and the type of set operation identified in the request, records that satisfy the set operation are identified and output from the hash table.
