I realize the paint is still wet on 5.6 and it is not even GA yet but it would be wonderful if Percona would considering backporting the SELECT COUNT(*) improvements that were added to 5.7 for innodb.
As we have all experienced, this can be very frustrating on large innodb tables compared to myisam and sometimes we are using third-party code where this is hardcoded.
Thanks and keep up the great work, I mean that sincerely!
