Are your Database Backups Good Enough?

In the last few years there have been several examples of major service problems affecting businesses data: outages causing data inconsistencies; unavailability or data loss, and worldwide cyberattacks encrypting your files and asking for a ransom.

Database-related incidents are a very common industry issue- even if the root cause is not the database system itself. No matter if your main relational system is MySQL, MariaDB, PostgresQL or AWS Aurora -there will be a time where you will need to make use of backups to recover to a previous state. And when that happens it will be the worst time to realize that your backup system hadn’t been working for months, or testing for the first time a cluster-wide recovery.

Forget about the backups, it is all about recovery!

Let me be 100% clear: the question is not IF data …

MariaDB Track at Percona Live

Less than one month left until Percona Live. This time the Committee work was a bit unusual. Instead of having one big committee for the whole conference we had a few mini-committees, each responsible for a track. Each independent mini-committee, in turn, had a leader who was responsible for the whole process. I led the MariaDB track. In this post, I want to explain how we worked, which topics we have chosen, and why.

For MariaDB, we had seven slots: five for 50-minutes talks, two for 25-minutes talks and 19 submissions. We had to reject two out of three proposals. We also had to decide how many topics the program should cover. My aim here was to use the MariaDB track to demonstrate as many MariaDB unique features as …

End of an Era: Neither MC nor Continuent Attending Percona Live

Continuent have been a long term sponsor of the Percona Live conference, and the MySQL conference as it was before that, for many years. We have attended the conference both as a Diamond sponsor, and members of our staff attending and presenting our products and experience at the conference.

The nature of these conferences always changes over time, and we have seen over the last few years how the Percona Live conference has moved from being a pure MySQL conference to an open source database conference. Although Continuent continue to provide open source software and integrate with many open source databases, our core operation still revolves around MySQL clustering and replication for MySQL and Oracle.

Continuent is also evolving and changing and we are increasingly deploying and moving towards pure cloud-based environments, building and developing products that are used on the cloud or …

MySQL 8.0 roles

One of the most interesting features introduced in MySQL 8.0 is roles or the ability of defining a set of privileges as a named role and then granting that set to one or more users. The main benefits are more clarity of privileges and ease of administration. Using roles we can assign the same set of privileges to several users, and eventually modify or revoke all privileges at once.

Roles in a nutshell

Looking at the manual, we see that using roles is a matter of several steps.

(1) Create a role. The statement is similar to CREATE USER though the effects are slightly different (we will see it in more detail later on.)

PerconaLive Amsterdam 2016 - Talks and shows

With Oracle Open World behind us, we are now getting ready for the next big event, i.e. the European edition of PerconaLive. I am going to be a presenter three times:

Attendees who want to play along can do it, by coming prepared with Docker 1.11 or later and the following images already pulled (images with [+] are mandatory, while [-] are optional):

Lightning talks at Percona Live Amsterdam: come on stage!

The schedule to Percona Live Europe 2016 is being finalized. It should be published soon, and it will include 3 hour and 6 hour tutorials, regular 50-minute talks, and shorter 25-minutes talks. It will not include, however, the lightning talks, a session comprising several 5-minute talks, and they are missing from the initial schedule for two reasons:

  • We want to offer a chance to all attendees to propose a lightning talk for some time. We would like to have more quality material to choose from.
  • They will not be in the conference venue. Instead, they will be hosted at Booking, during the community dinner.

Unlike in previous editions, though, the lightning talks will …
