One upgrade to rule them all



Up to now, the way of updating dbdeployer was the same as installing it for the first time, i.e. looking at the releases page, downloading the binaries for your operating system, unpacking it and finally replacing the existing binaries.

This is not the procedure I follow, however, as for me updating means just compile the latest version I have just finished coding. For this reason, when Simon Mudd mentioned to me that dbdeployer should update itself over the Internet, I didn’t immediately grasp the concept. But then …

LKML: Live patching for 3.20

https://lkml.org/lkml/2015/2/9/534

Building on the original kSplice idea and combining the efforts of the work done at Red Hat and SuSE, common infrastructure is now ready to be put into the Linux 3.20 mainline kernel – Red Hat and SuSE have already committed to using this.

I still reckon it’s freaky trickery, but heck – it works, and it’s great for server environments that have no redundancy (I prefer to fix that issue!) and can’t afford any downtime.

How to install MySQL 5.6 on CentOS 7

A bit of history

The latest version of Red Hat Enterprise Linux, one of the most popular and respected Linux distributions in the server market, was released in June 2014, followed by CentOS 7 and Oracle Linux releases in July of the same year.

There are very interesting changes for database administrators in these new releases, among which I would like to highlight the fact that installer now chooses XFS as its filesystem by default, which substitutes ext4 as the preferred format for local data storage. Red …

Fast Updates with TokuDB

With TokuDB v6.6 out now, I’m excited to present one of my favorite enhancements: fast updates with TokuDB. Update intensive applications can have their throughput limited by the random read capacity of the storage system. The cause of the throughput limit is the read-modify-write algorithm that MySQL uses when processing update statements. MySQL reads a row from the storage engine, applies the updates to it, and then writes the new row to the storage engine. To address this throughput limit, TokuDB uses a different update algorithm that simply encodes the update expressions of the SQL statement into tiny programs that are stored in an update Fractal Tree® message. This update message is injected into the root of the Fractal Tree index. …
