> The hybrid hash join algorithm is well known as the best join algorithm which takes advantage
of more available memory. The goal of this proposal is to implement HybridHashJoinExec class
subclassed from PhysicalExec. Its original literature is "Join processing in database systems
with large main memories" (http://www.cs.ucr.edu/~tsotras/cs236/W13/join.pdf). In addition,
you could find many other materials available in the web.
