Examples of EquiMatrixAssignment

plan_runner.thetajoin.matrix_mapping.EquiMatrixAssignment
@author ElSeidy This class performs region assignments to Matrix. i.e. Giventhe dimensions (S & T) & number of reducers (r), tries to find an efficient mapping of regions, that would be equally divided among "All" the reducers r. - More specifically find the dimension of the regions (reducers) matrix. - The regions are NOT essentially squares !! We are not following the same procedure of the Theta-join paper, for fallacies.
