Subject [GitHub] spark pull request: SPARK-11258 Remove quadratic runtime complexit...
Date Fri, 23 Oct 2015 13:13:10 GMT
Github user FRosner commented on the pull request:
    @felixcheung it is strange. When I did some performance checks today, the run time did
not seem to be quadradic. Is it maybe because the map transformation in the original code
is lazy and only executed when you actually access the data?
    I can tell you that the original implementation did not succeed on our file while mine
did. I will investigate a bit more. Maybe someone else has an opinion?
