The promise of DBaaS like RDS is to reduce operational overhead (among other things) and one of the stellar cases is upgrades (major and minor). The suggested procedure involves just a couple of steps. For example, using AWS Console, you can enable “Auto minor upgrade” or modify the DB instance and schedule the upgrade to run in the next maintenance window.

But, both these options are risky because the upgrade process will start during the maintenance window but it is NOT guaranteed that the upgrade will be completed within the specified duration. 

The Problem

RDS performs a few extra steps to ensure the data consistency and rollback, making the minor version upgrade a time-consuming process:

• It takes a backup (if automated backups are enabled) prior to starting the upgrade process.
• Performs slow shutdown after setting …

A few days ago I wrote about how grossly outdated statistics returned through MySQL’s Information_Schema can be. In that post, Øystein Grøvlen suggested taking a look at mysql.innodb_table_stats and mysql.innodb_index_stats as a better source of information. Let’s do just that!

Let’s start with the good news. Unlike MySQL Data Dictionary Tables (mysql.table_stats, etc),  mysql.innodb_table_stats and mysql.innodb_index_stats can be queried by the user. They also contain a lot of interesting statistics. Before we get to that though, let’s examine where those tables come from in more detail.

As the manual tells us, these tables are storing …
