-------------------------------------------------------------------
See uploaded scale tests.
Observations:
* without using max_RHS and max_LHS values, it runs up to 1.5x faster than 1.16
* with max_RHS and max_LHS set, it runs much faster e.g., with max_RHS=1 runs
20x faster

> Project: Apache MADlib
> Issue Type: Improvement
> Components: Module: Association Rules
> Reporter: Frank McQuillan
> Assignee: Orhan Kislal
> Priority: Major
> Fix For: v1.17

> Attachments: Association rules informal scale test - Sheet1.pdf,

> Goal is to speed up rule generation. The arules package in R limits posterior
> to 1.
> In MADlib the goal of the feature is to allow users to specify number of
> posterior items to 1 or 2 or ... with the goal of reducing run-time.
> Does it make sense to specify number of anterior items too?
