The latest from the MySQL community

My favorite way of MySQL installation is to go with tar ball.

It is easy, simple and manageable.

There is also other thoughts people would think the tarball has many limitations and restrictions in terms of package dependency and functional incompatibility with the OS. 

If certain functions are not available in generic tarball but they are available in rpm or package bundle, tarball may not be the choice.

The platform to go for is for those with the package repository (yum or apt_get) support.  

Steps for installation  (This is only my way!!!)
1.   Remove any MySQL package from the OS  
      There is a chance the OS may come with packages of MySQL installation from community.   To make sure we have a clean environment, it is good to remove all of them.

2.   Using OS's package …

In this blog post,  I’ll look at how to catch slow and frequent queries with ProxySQL.

More and more people are using ProxySQL because it is a great tool and it can help DBAs a lot. But many people do not realize that it is more powerful than it looks. It has many features and possibilities. I am going to show you one of my favorite “tricks” / use cases.

There are plenty of blog posts explaining how ProxySQL works. I am not going to that again. Instead, let’s jump straight to the point. There is a table in ProxySQL called “stats.stats_mysql_query_digest”. It is one of my favorite tables because it basically records all the queries that were running against ProxySQL. Without collecting any queries on the MySQL server, I can find …

As for each previous version, to upgrade to MySQL 8.0 you must first read the upgrade section in the manual. It’s important to know that you should upgrade without skipping a major version, so upgrade from 5.6 to 8.0 is not supported neither recommended.

Please also note that upgrades from any MySQL 8.0 RC won’t work. We support upgrade process only from GA versions.

Then one of the most important section to be aware of, is the incompatibility changes brought with the new version.

Once you have read the upgrade section in the manual and the release note of the version you want to install, with MySQL 8.0 and its new MySQL Shell, we developed …

In this blog post, I’ll look at how to execute a MySQL single table Point-In-Time Recovery.

I recently wrote a blog post describing a different way of doing Point-In-Time Recovery (PITR). If you want to know the step by step, please visit the mentioned blog post. Here is a quick summary of the approach:

4. Configure server from the first step as a slave from a fake master

In addition to the above steps, there is a similar approach …
