By default in MySQL 5.6, each time MySQL is
started (regular start or crash recovery), it iterates through
all the binlog files when GTIDs are not enabled. This can take a
very long time if you have a large number of binary log files.
MySQL and Percona Server 5.6.21+ have a fix with the

As with all my talks, I am not simply reading the slides so it really is worth to listen to the audio rather than just glance through the slide deck.
There were a number of great questions asked which I’ll answer below:
Q: How does Stewart feel about this version of 5.6 taking into consideration “Stewart’s .20 rule?” (ref 2013 Percona Live Conference).
A: For those who aren’t familiar with it, I have a rule which I call “Stewart’s dot twenty rule” which I’ve posted a few times about on my personal blog. It …[Read more]
