Changed defaults between MySQL 5.6 and 5.7
+0 Vote Up -0Vote Down

MySQL 5.7 comes with many changes. Some of them are better explained than others.

I wanted to see how many changes I could get by comparing SHOW VARIABLES in MySQL 5.6 and 5.7.

The most notable ones are:

  • binlog_format: the default is now ROW. This variable affects the format of the binary log, whether you use it as a backup complement or for replication, …

innodb_fast_checksum=1 and upgrading to MySQL 5.6
+0 Vote Up -0Vote Down

The Percona version of MySQL has been such a good replacement for the generic MySQL version that many of the features and options that existed in Percona have been merged into the generic MySQL.

Innodb_fast_checksum was an option added to improve the performance of checksums.

The system variable was replaced by innodb_checksum_algorithm in 5.7.

Unfortunately, when you go to upgrade from Percona 5.x to Percona (or generic mysql) 5.6, an in-place upgrade will fail.

The error(s) will be …

HowTo: Offline Upgrade of Galera Cluster to MySQL 5.6 or MariaDB 10
+0 Vote Up -0Vote Down

MySQL 5.6 has an extensive list of new features and changes, so upgrading from a previous version can be risky if not tested extensively. For this reason, we recommend our users to read and understand the changes before doing the upgrade. If you are on older MySQL versions, it is probably time to think about upgrading. MySQL 5.6 was released in February 2013, that’s almost two years ago!

A major upgrade, e.g., from MySQL 5.5 to 5.6 or MariaDB 5.5 to 10, requires the former MySQL/MariaDB server related packages to be …

Making MySQL Better More Quickly
+1 Vote Up -0Vote Down

With the upcoming release of MySQL 5.7 I begin to see a problem which I think needs attention at least for 5.8 or whatever comes next.

  • The GA release cycle is too long, being about 2 years and that means 3 years between upgrades in a production environment
  • More people use MySQL and the data it holds becomes more important. So playing with development versions while possible becomes harder.  This is bad for Oracle as they do not get the feedback they need to adjust the development of new features and have to best guess the right choices.
  • Production DBAs do want new features and crave them if it makes our life easier, if …

The Road to MySQL 5.6: Default Options
+0 Vote Up -0Vote Down

When you're testing out a new version of MySQL in a non-production environment there is a temptation to go wild and turn on all kinds of new features.  Especially if you're reading the changelogs or the manual and scanning through options.  You want to start with the most reasonable set of defaults, right?  Maybe you're even doing benchmarks to optimize performance using all the new bells and whistles.

Resist the temptation!  If your goal is to upgrade your production environment then what you really want is to isolate changes.  You want to preform the upgrade with as little to no impact as possible.  Then you …

+0 Vote Up -0Vote Down


Percona XtraDB Cluster 5.6 has been GA for several months now and people are thinking more and more about moving from 5.5 to 5.6. Most people don’t want to upgrade all at once, but would prefer a rolling upgrade to avoid downtime and ensure 5.6 is behaving in a stable fashion before putting all of production on it.

Password expiration policy in MySQL Server 5.7
Employee +1 Vote Up -0Vote Down

I’ve previously noted my wish to have a comprehensive password policy in MySQL Server.  MySQL Server 5.7.4 takes a significant step towards this goal by adding native support for enforcing password lifetime policy.  This complements the validate_password plugin introduced in MySQL Server 5.6, which helps ensure …
