Great stuff, Keith! I particularly appreciated you showing how to remotely monitor your MySQL Cluster running on Rasperry Pi. I know you only had a couple of instances, but want to also draw attention to the “Add Bulk MySQL Instances” button and associated workflow – it makes adding monitoring of tens or even hundreds of MySQL instances a 30-second proposition. It’s a great way to evaluate MEM 3.0 without installing software on every box or spending hours configuring instances one-by-one.

At MySQL Connect 2013, I talked about how we used MySQL 5.6 at Facebook, and explained some of new features we added to our Facebook MySQL 5.6 source tree. In this post, I'm going to talk about how we made full table scan faster in InnoDB.

Faster full table scan in InnoDB  In general, almost all queries from applications are using indexes, and reading very few rows (0..1 on primary key lookups and 0..hundreds on range scans). But sometimes we run full table scans. Typical full table scan examples are logical backups (mysqldump) and online schema changes (SELECT ... INTO OUTFILE).

 We take logical backups by mysqldump at Facebook. As you know MySQL offers both physical and logical backup commands/utilities. Logical backup has some advantages against physical backup. For example:

• Logical backup size is much smaller. …

Interview with Mats Kindahl, a MySQL Senior Software Engineer, on MySQL Fabric.

The order in which Galera cluster nodes must be started has long been an unjustly controversial topic. From time to time people ask how to restart the cluster in our mailing list. And from time to time they keep on making mistakes, like the one described here.

It happens so that people tend to believe in miracles. Worse, they tend to expect miracles to actually happen. They tend to expect, for example, that Galera cluster should automatically resync itself on startup to the "correct" position regardless of the order in which nodes are started. And are very disappointed to learn that it is not the case and one needs to choose the first node in the cluster with extreme care. After all joining a new node is completely automatic, no?

Considering that Galera cluster was designed to be "highly-available" …

Time to install MEM 3.0, and get its built-in agent working.

[ If you want some tips on What's New, have a look here. ]

I’ve downloaded the Monitor Server and the agent zipped s/w for Linux & Win from http://edelivery.oracle.com:

mysqlmonitor-3.0.0.2887-linux-x86-installer.bin
mysqlmonitoragent-3.0.0.2887-linux-glibc2.3-x86-32bit-installer.bin
mysqlmonitoragent-3.0.0.2887-windows-installer.exe

The Monitor install

So, on my Oracle Linux machine:

./mysqlmonitor-3.0.0.2887-linux-x86-installer.bin

It all installs fine. No issues, if you’re used to MEM 2.3.

Double check your configuration_report.txt :

MySQL Enterprise Monitor (Version 3.0.0.2887 : 3.0.0.2887)

Here are the settings you …

NOTE: This is part 1 of what will be a two-part series on the performance implications of using in-flight data encryption.

Some of you may recall my security webinar from back in mid-August; one of the follow-up questions that I was asked was about the performance impact of enabling SSL connections. My answer was 25%, based on some 2011 data that I had seen over on yaSSL’s website, but I included the caveat that it is workload-dependent, because the most expensive part of using SSL is establishing the connection. Not long thereafter, I received a request to conduct some more specific benchmarks surrounding SSL usage in MySQL, and today I’m going to show the results.

First, the testing …

MySQL Connect Conference was a great success and I am really happy for being
able to attend it this year. Oracle showed interesting improvements and
exciting features in the upcoming MySQL 5.7 and released a very early alpha
version of MySQL Fabric which is a framework for managing farms of MySQL
servers.

You can find the presentations about MySQL Fabric on SlideShare:

  . MySQL Sharding: Tools and Best Practices for Horizontal Scaling
  . MySQL High Availability: Managing Farms of Distributed Servers
