Hi!
In attached example I create join cursor with 3 conditions on "index:main:index1", "index:main:index2" and "table:main", and after getting all results from join cursor, I want to see join statistic for every index and for table. I am trying to get it as follows:
WT_CURSOR *statcur; WT_CALL(session->open_cursor(session, "statistics:join", jcursor, NULL, &statcur)); while (statcur->next(statcur) == 0) { const char *desc, *pvalue; uint64_t value; WT_CALL(statcur->get_value(statcur, &desc, &pvalue, &value)); printf("%s=%s\n", desc, pvalue); }
But i see statistic only for "index:main:index1":
$ LD_LIBRARY_PATH=wiredtiger-2.7.0_develop ./jcursor_full_stat
value from jcursor: key = 58, v1 = 58, v2 = 8
value from jcursor: key = 68, v1 = 68, v2 = 8
value from jcursor: key = 78, v1 = 78, v2 = 8
value from jcursor: key = 88, v1 = 88, v2 = 8
join: index:main:index1: accesses=4
join: index:main:index1: actual count of items=90
join: index:main:index1: bloom filter false positives=0
How can I get statistic for others conditions?
