Here is a comment from a MADlib user that I recently heard: “No apparent way to set an upper bound for itemset size in assoc_rules function. This results in it running forever with larger data sets. In the R "arules" package, you can set a max itemset size so that it doesn't look for unnecessarily large associations.” https://cran.r-project.org/web/packages/arules/arules.pdf
Does a single optional parameter make sense to add to http://madlib.incubator.apache.org/docs/latest/group__grp__assoc__rules.html similar to the maxlen parameter in “arules” ? Any other considerations here or improvements to make the this algorithm at the same time? minlen? Thanks, Frank
