Fun with Bugs #41 - Bugs Fixed in MySQL 5.7.11
+0 Vote Up -0Vote Down

I've just noted that Oracle had released new versions of MySQL on February 5, 2016 formally, so while these days I am mostly thinking about the ways to do support properly, remembering my colleagues and trying to understand some of RocksDB internals, it's time to postpone all these and write about bugs again. This time about some of the public bug reports from MySQL Community and Oracle engineers that were fixed by Oracle in MySQL 5.7.11.

As usual, I'll try to mention who had reported a bug and who verified it, as I think that names …

Measuring Percona Server Docker CPU/network overhead
+0 Vote Up -0Vote Down

Now that we have our Percona Server Docker images, I wanted to measure the performance overhead when we run the database in the container. Since Docker promises to use a lightweight container, in theory there should be very light overhead. We need to verify that claim, however. In this post I will show the numbers for CPU and network intensive workloads, and later I will take a look …

MySQL Community Awards 2016: Call for Nominations!
+1 Vote Up -0Vote Down

The 2016 MySQL Community Awards event will take place, as usual, in Santa Clara, during the Percona Live Data Performance Conference, April 2016.

The MySQL Community Awards is a community based initiative. The idea is to publicly recognize contributors to the MySQL ecosystem. The entire process of discussing, voting and awarding is controlled by an independent group of community members, typically based of past winners or their representatives, as well as known contributors.

It is a self-appointed, self-declared, self-making-up-the-rules-as-it-goes committee. It is also very aware of the importance of …

MariaDB JIRA is moving
+0 Vote Up -0Vote Down

The MariaDB JIRA instance that currently is in use for project and issue tracking will change. The current instance is hosted in Atlassian’s cloud and it has worked well, but we have hit the maximum user limit of 2000 users. It’s fantastic to see how many of you actually report bugs and other issues in the MariaDB […]

The post MariaDB JIRA is moving appeared first on MariaDB.org.

MySQL Connector/Python currently not available from PyPI
Employee +1 Vote Up -0Vote Down

With PEP 470 now requiring files to be hosted on PyPI, you may have noticed that MySQL Connector/Python is now no longer available using the pip-tool.

The MySQL Engineering team at Oracle really would like to have the connector available through PyPI and have been talking with the Python Foundation towards that. We know users and developers of OpenStack, for example, have requested this as well as lots of other Python users.

For now …

MySQL Support People - Percona Support
+1 Vote Up -0Vote Down

I planned to continue this series of posts with the one about MySQL Support engineers who joined us in Oracle while I was working there, but based on recent events in my life I'd prefer to postpone it and move directly to the team I worked for during last 3+ years, Percona Support Team.

Disclamer: In the list below I still try to pay attention to public contribution by each of engineers mentioned to MySQL Community, mostly in a form of bug reports. This is not the only way they contributed, but I have to stick to this format in current series of posts. I also base my comments mostly on my memory and quick search of public …

New Query Rewrite Presentation at FOSDEM 2016
Employee_Team +1 Vote Up -0Vote Down

Last weekend I had the pleasure to attend the excellent FOSDEM conference in Brussels, Belgium. I indulged aplenty in pancakes with Nutella, a Belgian beer or two, and some truly interesting presentations. MySQL had a lecture hall for itself the whole weekend, and the booth conveniently located outside.…

How To Speed Up MySQL Restart (hint: just like before, but this time for real)
+0 Vote Up -0Vote Down

Restating MySQL can be really annoying. You just want to disable the goddamn query cache and it takes forever (read 5-10 minutes) to shutdown, not to mention the warm-up time. Yes, with MySQL 5.7 you can do may changes online, so you won’t necessarily be restarting that often, but you still need to do upgrades, occasionally increase redo log size and, admit it, enable skip-grant-tables. Here’s how you can make this process way less painful.

Why is MySQL so slow to restart?

Before we go any further, let me tell you right away that when I’m speaking about MySQL here, I’m actually speaking about InnoDB, or rather, a MySQL server that’s …
