i am interested in the performance of in memory join queries on tokudb and innodb and, for innodb, i would like to know how many key comparisons were needed when running the query. i counted the number of calls to a function called "cmp_dtuple_rec_with_match". does this include ALL of the key comparisons? thanks rich prohaska
