MySQL Shell makes it easy to develop tools you can use for example to generate reports. In a previous blog, I showed how to use external modules in MySQL Shell. In this blog, I will take it one step further and use the curses Python module to create auto-refreshing reports. The first example will be kept very simple to show the idea, then a more realistic example will be shown where the top N files sorted by I/O will be returned.

Note

Out of the box, this does not work on Windows as Python does not ship with the curses library.

Basic Example

As a basic example, consider the query SELECT NOW(). This returns …

Recently, I did some maintenance on Innotop and I merged several pull requests including one to support MySQL 8.0 (thank you yoku0825 for the contribution).

As you know, Innotop is written in Perl and to be able to use it with MySQL 8.0, you need to have Perl DBD for MySQL compatible with MySQL 8.0 too (a driver that support the new default authentication plugin, caching_sha2_password).

The other day, I was reading a blog by Magnus Hagander about tracking foreign keys throughout a schema in PostgreSQL. I thought it was a good idea, so I decided to look at how you can track foreign key in MySQL.

The way I decided to do it was to start out with a table, then find all tables referencing the table by a foreign key. From this basic (and simple as it will be shown) query, it is possible to create a chain of relations. The key table for the queries is …
