MySQL 8.0 brings a lot of new spatial features. The main feature is the support for multiple spatial reference systems (SRSs).

Spatial reference systems is not a new concept in MySQL, but 8.0 is the first version where it affects computations, and it’s the first version where users actually have to think about it.…

We have been told many times that modifying live database should be done with extreme care, we should always make a backup before doing something big to the database. However, there are countless stories on the Internet about losing data due to various reason, one of them is forgetting to create a backup (Gitlab is an example: https://about.gitlab.com/2017/02/01/gitlab-dot-com-database-incident/). I was facing the same issue when upgrading MySQL server to a new version. Luckily I was able to restore most of the data but it was still a very good lesson for me. One of lesson I learned is how we could restore the data from the *.ibd and *.frm file.

The database I worked with had many tables. There were about 5 of them using MyISAM engine while others were using InnoDB engine. I was asked to upgrade …

MySQL 8.0 has been released as stable (GA) earlier this month. For db4free.net this means it’s time to make MySQL 8.0 the default version and to deprecate the MySQL 5.7 server instance.

The new MySQL 8.0 server is running on the default port 3306. All new registrations will have the database created on this server. It is fresh and empty and will start from scratch.

The previous MySQL 5.7 server will remain available on port 3308. All users who have data there which they want to keep should migrate it to the new MySQL 8.0 server. This will require you to sign up again.

The previous MySQL 8.0 server will remain on port 3307. Both the old MySQL 5.7 and the old MySQL 8.0 server on port 3307 will be available until June 15, 2018. Data which isn’t migrated to the new server instance by then will be lost.

The new MySQL 8.0 server instance will come …

What does Anton Ego – a fictional restaurant critic from the Pixar movie Ratatouille – have to do with MySQL 8.0 GA?

When it comes to being a software critic, a lot.

In many ways, the work of a software critic is easy. We risk very little and thrive on negative criticism, which is fun to read and write.

But what about those who give their many hours of code development, and those who have tested such code before release? How about the many people behind the scenes who brought together packaging, documentation, multiple hours of design, marketing, online resources and more?

And all of that, I might add, is open source! Free for the world to take, copy, adapt and even incorporate in full or in part into their own open development.

It is in exactly that area that the …

The requirements for managing and running a database in a modern enterprise have evolved over the past ten years. Those in charge of running enterprise databases have seen their focus shift from ensuring access and availability, to architecture, design and scalability responsibilities. Web-first companies pioneered the change by charging site reliability engineers (SRE’s) or multi-faceted DBAs with the task of ensuring that the company’s main revenue engine not only stayed up, but could scale to wherever the business needed to go. This is a far cry from the classic enterprise DBA’s top responsibilities: keep it up, keep it backed up, and react to issues as they present themselves.

Today, enterprises look for new revenue models to keep up with a shifting technology paradigm driven by the cloud. The requirements and needs for managing their database environments are changing along with this shift. In the SaaS world, application outages …
