how MySQL engineering broke the backups

MySQL has exceptional track of record by introducing minor fixes that cause major breakages. Though usually I could blame naiveté of engineers, who did not really ever have to deal with production implications, but lately I can start sensing various business implications against open-source offerings.

As an original author of mydumper I really cannot get out of my mind that 5.5 and 5.6 metadata locking changes are there to screw with anyone who is building a backup solution using stable snapshot views of MySQL (for example, mysqldump –single-transaction, the golden standard of backing things up in MySQL world).

As seen in a bug #71017 (palindrome!) filed by my esteemed colleague Eric, newly introduced behaviors …

The following SQL statements create two databases and grant appropriate privileges to the student as the root superuser:

/* Create two databases. */
CREATE DATABASE seussdb;
CREATE DATABASE appdb;
 
/* Grant privileges to a student user. */
GRANT ALL ON seussdb.* TO student;
GRANT ALL ON appdb.* TO student;

Log out from the root superuser and reconnect as the student user. Then, the following code connects to the seuss

Log Buffer #346, A Carnival of the Vanities for DBAs

Economist says that Physics suggest that storms will get worse as the planet warms. Typhoon Haiyan in Philippines, bush-fires in Australia, floods in China, and extreme unpredictable weather across the planet is a sober reminder. Good news is that technology and awareness is rising, and so is the data. Database technologies are playing their part to intelligently store that data and enabling the stakeholders to analyze and get meaningful results to predict and counter the extreme conditions. This Log Buffer Edition appreciates these efforts.
