"Latest symlink"A "latest" symlink, is a symbolic link (on Linux, Unix etc) which links to the "latest" version of a file.
Suppose we have a file which takes some effort to create, which is generated periodically or in response to some stimulus (e.g. user activity). Then we want to create a "latest version" symlink.
Ideally the properties should be

• latest symlink always points at the latest version (duuh!)
• latest symlink always exists
• latest symlink never points at a partially completed, broken, missing or otherwise bad file

Sometimes people do this in a way which won't work.

The classic MySQL command line tool is how most users – developers and administrators – interact with a MySQL server. From administrative tasks to trying out queries, it wouldn’t be far-fetched to call it the face of MySQL.

With a new programming interface built into the MySQL Server, we need to properly support it at the client side in connectors, tools and of course, the command line client.…

The recently released 1.4.1 version of MariaDB MaxScale contains a bundle of great improvements to the Database Firewall Filter, dbfwfilter.

We had the first MariaDB Berlin Meetup on Tuesday 12.04.2016 at the Wikimedia Berlin offices at 7pm. More or less there were over 54 people that attended the event, a mix of MariaDB Corporation employees and community members. We competed with the entertainment at the AWS Summit Berlin which was apparently about 400m away! Food and drink were enjoyed by all, and most importantly there were many, many lightning talks (minimum 5 minutes, maximum 10 minutes – most were about 6-7 minutes long).

The bonus of all of this? Lots and lots of slides for you to see. Grab them from the Google Drive folder MariaDB Berlin meetup April 2016.

Please be aware that the following scripts and settings in this post are not production ready (missing error handling, etc.) –  this post is just a proof of concept.

What is Orchestrator-agent?

Orchestrator-agent is a sub-project of Orchestrator. It is a service that runs on the MySQL servers, and it gives us …
