This project realizes some common relational operators on top of Phoenix.
Phoenix is a shared-memory implementation of Google's MapReduce model for data-intensive processing tasks. Phoenix can be used to program multi-core chips as well as shared-memory multiprocessors (SMPs and ccNUMAs).
Here I have written the MapReduce jobs over Phoenix's C API needed to implement the most common relational operators:
Select, Project, Sort, Aggregate (but not yet Join)
The project is a proof of concept abstraction layer over Phoenix's MapReduce API, simplifying its usage while keeping the MapReduce details concealed to the user.
