This post is an introduction on how to use the new support  for spatial data types with Entity Framework 5.0 on applications with MySQL and Connector/Net.

The MySQL Connect conference is a great opportunity to listen to and chat with people from the MySQL community – including the engineers who work on or around MySQL as well people who are using it in production. The conference takes place from 21-23 September in San Francisco (runs up to Oracle OpenWorld). There are 84 sessions scheduled and the content catalog has now been published.

You can take Oracle's MySQL Database Administrator training on five continents. In this 5-day, live, instructor-led course, you learn to install and optimize the MySQL Server, set up replication and security, perform database backups and performance tuning, and protect MySQL databases.

Below is a selection of the in-class events already on the schedule for the MySQL for Database Administrators course.

Among all of the excellent events going on like YAPC, Velocity, and Percona MySQL University, we recently released Percona Toolkit 2.2.3. It’s a small update that includes the following:

• pt-online-schema-change did not handle the failure of the DROP TRIGGER statements correctly
• Created pt-agent
• pt-query-digest –output json now includes more data

The pt-online-schema-change issue had a high importance. The bug fix is bug …

After speaking about the topic the Developer Week 2013 in Nürnberg this week, due to some scheduling coincide I repeated it today for our codecentric "Dev-Friday" in which internal or external speakers present some topic to the whole company.

For a while we have been recording these for colleagues on vacation or otherwise occupied during the talk to watch it later. Several of them are available on codecentric's YouTube channel publicly. As of a few moments ago, so is my "Man in the Middle? – No, thank you!" talk on the possibility of – and countermeasures against – man in the middle attacks against SSL connections.

For your convenience, here is the video:

MySQL Enterprise Backup (MEB) is the ideal solution for backing up MySQL databases. MEB 3.8.2 is released in June 2013.

MySQL Enterprise Backup 3.8.2 release’s main goal is to improve usability. With this release, users can know the progress of backup completed both in terms of size and as a percentage of the total. This release also offers options to be able to manage the behavior of MEB in case the space on the secondary storage is completely exhausted during backup.

The progress indicator is a (short) string that indicates how far the execution of a time-consuming MEB command has progressed. It consists of one or more "meters" that measures the progress of the command. There are two options introduced to control the progress reporting function of mysqlbackup command (1) –show-progress (2) –progress-interval.

The user can control the progress indicator by using “--show-progress” option in …

With the last Percona XtraDB Cluster (PXC) release, two major features were added:

* a new command to bootstrap the cluster was added to the init script
* SST via Xtrabackup now supports Xtrabackup 2.1 features

In this post, I want to explain the benefits of these added features and how to use them.

If you follow the mysqlperformanceblog regularly, you’ve already noticed that there are several ways to start a node and that it’s not always easy to start the node that is supposed to bootstrap the entire cluster.

I’m about to start working through converting a large MySQL installation to InnoDB. For the particular use case durability is desired, and with MyISAM a loss of power almost certainly guarantees data loss. Durability is not available as an option.

So the normal question people ask is.. okay, what do I pay for this feature?

I think if you are looking at the workload in question I actually believe InnoDB will perform better overall. Row-level locking, multiversion concurrency control, and the correct selection of hardware (fast-disks with a RAID controller + batter backed write cache) will really help it shine.

But my problem is that InnoDB could be better in 9 situations, and worse in 1. What matters …
