Abstract
In one aspect, a computer-implemented method includes detecting, by a server includes one or more processors, a request to perform a hash join operation on a data structure stored in a data storage device, forming a hash lookup dictionary based on lookup results in a hash table, storing the hash lookup dictionary in a cache, and probing, during a probing phase of the hash join operation, the cache.
