Tab Sweep – MySQL ecosystem edition

Tab housekeeping but I also realise that people seem to have missed announcements, developments, etc. that have happened in the last couple of months (and boy have they been exciting). I think we definitely need something like the now-defunct MySQL Newsletter (and no, DB Weekly or NoSQL Weekly just don’t seem to cut it for me!).

MyRocks

During @scale (August 31), Yoshinori Matsunobu mentioned that MyRocks has been deployed in one region for 5% of its production workload at Facebook.

By October 4 at the …

MySQL Support Engineer's Chronicles, Issue #4

This week I had to deal with some unusual problems. But let me start with Percona's xtrabackup, software that I consider a key component of many current production MySQL setups and use regularly. Recently new minor versions of XtraBackup were released, check the details on 2.4.5, for example. It made a step towards support of MariaDB 10.2, but it's still a long way to go, see this pull request #200.

My main problem with xtrabackup, though, is not with lack of support of MariaDB 10,2-specific features. Why should they care, after all... The problem is that old well known bugs and problems are not resolved, those that may affect all MySQL versions, forks and environments. Check  …

MySQL Support Engineer's Chronicles, Issue #3

The original idea of this series was to publish one post per week, but it seems every other week I have some special topic that well deserves a dedicated post. Last week I had no time to complete my writing because of long (and, I hope, useful) Howto post on replacing corrupted partition using non-corrupted one from other server in replication setup. But I had links and notes collected in a draft that I am going to complete now.

First of all, during the previous week I had time to submit two more talks for the  …

Dockerizing MySQL at Uber Engineering

The post Dockerizing MySQL at Uber Engineering appeared first on Uber Engineering Blog.

Percona Poll: What Database Technologies Are You Using?

Take Percona’s poll on what database technologies you use in your environment.

Different databases get designed for different scenarios. Using one database technology for every situation doesn’t make sense, and can lead to non-optimal solutions for common issues. Big data and IoT applications, high availability, secure backups, security, cloud vs. on-premises deployment: each have a set of requirements that might need a special technology. Relational, document-based, key-value, graphical, column family – there are many options for many problems. More and more, database environments combine more than one solution to address the various needs of an enterprise or application (known as polyglot persistence).

Please take a few seconds and answer the following poll on database technologies. Which are you using? Help …

Fixing Broken MySQL Replication: Basic Usage of pt-table-checksum, pt-slave-restart and pt-table-sync

For second day in a row I am trying to concentrate on writing a second issue for my new series of blog posts, but I can not complete. It seems half of it is going to be devoted to three tools from Percona Toolkit that I had to remember and explain this week: pt-table-checksum, pt-table-sync and pt-slave-restart. So, I decided to write a separate post on this topic.

The context was simple: in the middle of (the weekend) night customer comes with broken replication issue, without a fresh backup from master or with few gigabytes …

Update the Signing Key for Percona Debian and Ubuntu Packages

In this blog post, we’ll explain how to update the signing key for Percona Debian and Ubuntu packages.

Some of the users might have already noticed following warning on Ubuntu 16.04 (Xenial Xerus):

W: http://repo.percona.com/apt/dists/xenial/InRelease: Signature by key 430BDF5C56E7C94E848EE60C1C4CBDCDCD2EFD2A uses weak digest algorithm (SHA1)

when running apt-get update.

Percona .deb packages are signed with a key that uses an algorithm now considered weak. Starting with the next release, Debian and Ubuntu packages are signed with a new key that uses the much stronger SHA-512 algorithm. All future package release will also contain the new algorithm.

You’ll need to do one of the …

Speaking in October 2016
  • I’m thrilled to naturally be at Percona Live Europe Amsterdam from Oct 3-5 2016. I have previously talked about some of my sessions but I think there’s another one on the schedule already.

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:
