Traditionally, setting up high availability (HA) in MySQL has been a challenging task, especially for people without advanced knowledge of MySQL. From understanding concepts and technologies, to the tooling, specific commands and files to execute and edit, there’s a lot of things you need to know even when planning a test deployment (the Quick Start Guide for Group Replication should give you an idea).…

Today we are introducing a new MySQL feature called MySQL InnoDB Cluster. Make sure to watch the demo video on the MySQL YouTube Channel!

Find out more by looking into the MySQL InnoDB Cluster documentation.

If you got questions or feedback please feel free to post on the MySQL Forums.…

Introducing the new MySQL InnoDB Cluster Feature

MySQL has had good support for replication for a long time. After all, it is one of the key features that have enabled companies like Facebook, Booking, Twitter and so many others to grow and scale to such extreme scale with MySQL as their primary database engine.…

When I wrote this blog about “bash on Windows” a few days ago I omitted one issue, that I already knew about. This is because it needs some elaboration that did not ‘fit in’ the previous blog. So I will do it here.

It is about Unicode. Unicode always was a pain in “cmd” and with the arrival of “bash” in Windows, this has become more significant and important. Actually on any recent *nix platform user will not do anything to make Unicode work ‘out of the box’ in the console and display all or almost all scripts (though I have noticed that the completeness of the ‘monospace’ font mostly used in the Linux console varies between Linux distros – with …

Uber has been in the news for numerous reasons in the past few days. Be it expansion to new countries or selling its China operations to Didi chuxing, Uber is growing exponentially and expanding into newer markets. Recently, Uber also announced a major change – Changing their databases from Postgres to MySQL. While enterprises are constantly checking and trying to find the right fit for their databases, it takes immense research and analysis to decide on THE one.

Each enterprise has their own requirements and it is imperative for the company to decide on the database that suits their needs. This is exactly what Uber did. Uber recently shared a …

If you haven’t heard the news yet, MySQL 8.0 is apparently the next release of the world-famous database server.

Obviously abandoning plans to name the next release 5.8, Percona Server’s upstream provider relabelled all 5.8-related bugs to 8.0 as follows:

Reported version value updated to reflect release name change from 5.8 to 8.0

What will MySQL 8.0 bring to the world?

While lossless RBR has been suggested by Simon Mudd (for example), the actual feature list (except a Boost 1.60.0 upgrade!) remains a secret.

As far as bug and feature requests go, a smart google query revealed which bugs are likely …

I just joined Chocolatey, which is sort of like yum or apt-get for Windows. HeidiSQL was already listed there but was outdated, so I created a package with the current 9.3 release.

See the package here: https://chocolatey.org/packages/HeidiSQL

Certificate for installers and nightly builds

Finally I bought a certificate at certum.eu to sign the HeidiSQL installers and nightly build files. The latest built installer and nightly builds now don't show a warning message in Windows 7, 8 and 10 any longer. Instead, Windows 7 displays the certificate owner in a dialog when executing:

For all Open Source developers - here's my tutorial for obtaining and managing a code signing certificate using signtool.exe.

Markdown syntax support in this forum

After updating most webserver components on heidisql.com I thought I could add Markdown support to the forum. Markdown provides an easy-to-read, …

If you're one of the users having updated HeidiSQL this morning to revision 5002, then you will surely see a crash when starting heidisql.exe . This is due to an accidental commit of a file with unfinished changes from me. Sorry for that. I have just reverted that in revision 5003.

As the program crashes at the very start, you won't be able to update HeidiSQL automatically. As a solution, you can use the installer from that fixed build for updating:
32/64bit: http://www.heidisql.com/installers/HeidiSQL_9.3.0.5003_Setup.exe
32bit only: http://www.heidisql.com/installers/HeidiSQL_9.3.0.5003-32_Setup.exe

See this forum thread for details.

With the new GA release 6.3.5 we finally also managed to bring MySQL Workbench to Github. This is something we planned for quite some time and now the repository is part of the MySQL group at Github. Go Workbench…
