Hi Sergei,
thanks for your comments. Did you also review the first patch? revno: 4009 committer: Sergey Vojtovich <svoj@mariadb.org> branch nick: 10.0 timestamp: Fri 2014-02-14 16:25:41 +0400 message: MDEV-5674 - Performance: my_hash_sort_bin is called too often
- reduced number of my_hash_sort_bin() calls from 4 to 2 per query. Let MDL subsystem use pre-calculated hash value for hash inserts and deletes. - reduced number of memory accesses done by my_hash_sort_bin()
No. I thought there's only one, and reviewed the last as usual. Now I've looked for it and couldn't find this patch. There were few revno:4009 mail, but none about my_hash_sort_bin. And few "MDEV-5674" (really MDEV-5675), but none with revno:4009. Regards, Sergei
