Everything is awesome

My kids watched the new Lego movie today and spent the rest of the day repeating "Everything is amazing". I spent a few hours reading MongoDB documentation to help a friend who uses it. Everything wasn't awesome for all of us. I try to be a pessimist when reading database documentation. If you spend any time near production then you spend a lot of time debugging things that fail. Being less than optimistic is a good way to predict failure.

Setting Up an External OpenStack Testing System – Part 1

This post is intended to walk somone through the process of establishing an external testing platform that is linked with the upstream OpenStack continuous integration platform. If you haven’t already, please do read the first article in this series that discusses the upstream OpenStack CI platform in detail.

Using Percona rsync repositories to set up the local CentOS mirror

One of the more popular support requests we get involves setting up the official Percona rsync repositories that can be used to set up local mirrors. I’m glad to announce that this was implemented recently. You can now access the rsync repository at:rsync://rsync.percona.com/rsync/

Changing an async slave of a PXC cluster to a new Master using 5.6 and GTID

Before Percona XtraBackup 2.1.7 and Percona XtraDB Cluster 5.6.15-25.3, rsync was the only SST method supporting GTID in the way that it was possible to move an asynchronous slave from one Galera node to another one (related bug).

On the road again - FOSSAsia

On the road again - FOSSAsia

It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

Amber Alert: Worse Than Nothing?

In the last few years, there’s been a lot of discussion about alerts in the
circles I move in. There’s general agreement that a lot of tools don’t provide
good alerting mechanisms, including problems such as unclear alerts, alerts that
can’t be acted upon, and alerts that lack context.

Yesterday and today at the Strata conference, my phone and lots of
phones around me started blaring klaxon sounds. When I looked at my phone, I saw
something like this (the screenshot is from a later update, but otherwise
similar):

PERFORMANCE_SCHEMA vs Slow Query Log

A couple of weeks ago, shortly after Vadim wrote about Percona Cloud Tools and using Slow Query Log to capture the data, Mark Leith asked why don’t we just use Performance Schema instead?
