Renaming tables with MySQL Enterprise Backup 3.12.0
Employee +0 Vote Up -0Vote Down

Introduction

MySQL Enterprise Backup 3.12.0 (MEB) introduces a new feature for restoring an InnoDB table from a backup. Now it is possible to rename the table during restore. This is useful when the user wants to restore a table from a backup without overwriting the existing version of the table in the database.

The following example illustrates how the renaming feature could be used.  Suppose that the DBA has deleted three rows from a table T1 by mistake and he now wishes to get them back from a backup. He wants to leave the database online and to restore the 3 deleted rows from a …

Connector/Python 2.1.1 Alpha released with C Extension
Employee +1 Vote Up -0Vote Down

MySQL Connector/Python 2.1.1 took a while to release and that was because we had to add some more packages which contains the optional C Extension. Note that this is still Alpha and we want you guys to report any problems and requests.

The Connector/Python C Extension was added because in certain situations, for example reading a huge result set, can take a long time with pure Python. That’s why we choose to interface with …

Increasing Cloud Database Efficiency – Like Crows in a Closet
+0 Vote Up -0Vote Down

In Mo’ Data, Mo’ Problems, we explored the paradox that “Big Data” projects pose to organizations and how Tokutek is taking an innovative approach to solving those problems. In this post, we’re going to talk about another hot topic in IT, “The Cloud,” and how enterprises undertaking Cloud efforts often struggle with idea of “problem trading.” Also, for some reason, databases are just given a pass as traditionally “noisy neighbors” and that there is nothing that can be done about it. Lets take a look at why we disagree.

With the birth of the information age came a coupling of business and IT. Increasingly …

Oracle's 10 commitments to MySQL - a 5 year review
+0 Vote Up -2Vote Down

Last week passed the 5th anniversary of the closing of Oracle's acquisition of MySQL. That also means that the 5 year term of the infamous 10 commitments to MySQL users that Oracle made to the EU commission expire.

Since I work for another database technology nowadays, I have made a point of not blogging about MySQL related issues anymore (and mostly do not follow MySQL close enough to say anything wise). But in 2009 I was so closely involved in the EU investigation into the Oracle-Sun merger, that I feel this is a topic I could write a retrospective on. For nostalgic reasons if nothing else... In any case, these commitments have very …

Getting mutex information from MySQL’s performance_schema
+1 Vote Up -0Vote Down

We have been using SHOW ENGINE INNODB MUTEX command for years. It shows us mutex and rw-lock information that could be useful during service troubleshooting in case of performance problems. As Morgan Tocker announced in his blog post the command will be removed from MySQL 5.7 and we have to use performance_schema to get that info.

The documentation of MySQL also says that most of the command output has been removed from 5.6 and that we can find similar info in performance_schema. It doesn’t show any …
