Help MariaDB gather some statistics!

I was browsing around the Internet (don’t remember what for) and I accidentally found one cool aspect of MariaDB. There is a feedback plugin and this short post is meant to encourage you to use it!

Ok, so what it does and why should you opt-in to be spied on It takes some information about your MariaDB server including it’s usage and it will send it to the MariaDB folks. It doesn’t send private data from your database. It sends stuff like what OS are you running, what version of various plugins, how did you tweaked the default settings and also how big and how busy is your server. Now a short list of why I turned this on:

  • Why not? Doesn’t cost me anything, nothing from the data I send is secret.
  • When I develop an …

MariaDB and WebScaleSQL

On Thursday MySQL technology saw a huge boost. It’s hard for anyone now to argue that MySQL isn’t in the game of extreme scalability and performance, which some NoSQL vendors have been using as a tagline for the last years. To see four of the largest MySQL and MariaDB users come together to bootstrap a branch of MySQL for extreme scaling needs is simply fantastic. The improvements done inside these companies will now be available to the rest of the community. In all fairness Facebook and Twitter, in particular, have been making their improvements publicly available also before. Google has also made some improvements available publicly over the years and have lately been active in the MariaDB project with code reviews, bug fixes and other patches. But broadening the public contributions further and combining it all, is new.

Engineering of MySQL technology happens in many places. Aside from Oracle and the companies behind WebScaleSQL, …

MariaDB in Google Summer of Code 2014

MariaDB is participating in the Google Summer of Code 2014. Students are encouraged to propose a project before the deadline (this Friday!).

This is our second year participating, and as always we have an ideas page available. We also have a list of things we think are achievable in JIRA – check out our gsoc14 tag.

In 2013, we had three projects, of which two are in MariaDB 10.0: PCRE regular expressions and Roles. The other will be targeted towards MariaDB 10.1. There’s nothing like having GSoC students participate and …

Snippet: Fetching results after calling stored procedures using MySQL Connector/Python

Problem

Using MySQL Connector/Python, you are calling a stored procedure which is also selecting data and you would like to fetch the rows of the result.

Solution

For this example we create a stored procedure which is executing SHOW SLAVE STATUS.

cnx = mysql.connector.connect(user='scott', password='tiger',
                              database='mining')
cur = cnx.cursor()
cur.execute("DROP PROCEDURE IF EXISTS slave_status")
proc = "CREATE PROCEDURE slave_status () BEGIN SHOW SLAVE STATUS; END"
cur.execute()
cur.call("slave_status")

for result_cursor in cur.stored_results():
 for row in result_cursor:
   print(row[0])

The result from the above would be:

shell> python foo.py
Waiting for master to send event

Discussion

The stored_results() method of …

A followup on SHOW ENGINE INNODB MUTEX

In November, I wrote about the command SHOW ENGINE INNODB MUTEX and sought feedback as to how it continues to be used post introduction of performance_schema.

The outcome from this feedback is that the MySQL team has decided to remove this command from MySQL 5.7.

These decisions are not light ones for the team to make. I wanted to thank everyone for their feedback, and also share why this decision was an important one for the future of MySQL:

  1. By design, data collection for SHOW ENGINE INNODB MUTEX was always enabled, with no switch to disable it. We believe that for some workloads being able to disable the collection is useful, and in the case of performance_schema this is possible.
  2. performance_schema overlaps with this …
