Hyunsik Choi commented on TAJO-35:
----------------------------------
Looks good to me. The proposal is well-surveyed and contains well-written
approach and plan.
Firstly, you may need to dig Tajo source code. You can find more information
about Tajo from http://tajo.incubator.apache.org and
http://wiki.apache.org/tajo. Especially, "GettingStarted"
(http://wiki.apache.org/tajo/GettingStarted) is a good point to start, and
"HowToContribute" would be helpful for you.
TestBNLJoinExec and TestHashJoinExec are good starting points for understanding
physical operators. With these unit tests, you can also execute certain
physical operators.
Also, I would like to suggest you not to miss the deadline.

> 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.
