As of 8.0.16, the mysql_upgrade binary is deprecated, but its functionality is moved into the server. Let’s call this functionality the “server upgrade”. This is added alongside the Data Dictionary upgrade (DD Upgrade), which is a process to update the data dictionary table definitions.…

MySQL database management system, has been released.

The available downloads include both a Unicode driver and an ANSI
driver based on the same modern codebase. Please select the driver

The ST_DISTANCE function has been upgraded in MySQL 8.0.16 to allow you to specify the unit of measure between to locations.  Previously you had to convert from meters to what you desired but now you can use the INFORMATION_SCHEMA.ST_UNITS_OF_MEASURE table to help you get many of the more popular measurements (foot, yard, statue mile, nautical mile, fathom) and some ones that are new to me (chain, link, various feet).   However some measures are omitted (furlong,smoot) that may have some relevance in your life.

Generally you have much bigger benefit with dim_STAT when you're collecting and analyzing your data live (online). However, there maybe still many situations when this is simply not possible (due security restrictions, wide remote distance, or simply externally inaccessible hosts, etc.) -- for such cases dim_STAT has special tool EasySTAT allowing you to collect all the needed stats locally on the given machine, and then later to upload them to your dim_STAT server for post-analyze. To simplify overall setup, EasySTAT is integrated into STAT-service of dim_STAT and can be directly involved from there, also following the same rules for MySQL access and so on (e.g. if your STAT-service is already operational, then your EasySTAT will be too ;-))

The following article is explaining how to deploy and start EasySTAT …

In my blog yesterday, I wrote about the new reporting framework in MySQL Shell. It is part of the 8.0.16 release. I also noted that it includes the possibility to create your own custom reports and use those with the \show and \watch commands. This blog will explore how you can create a report and register it, so it automatically is available when you start MySQL Shell.

Update

This blog was updated on 30 April to include the use of the values argument for report options. This moved the validation of the optional arguments in to the reporting framework and automatically includes the list of valid options …

There are three different ways ProxySQL can direct traffic between your application and the backend MySQL services.

1. Locally, on the MySQL servers.
2. Between the MySQL servers and the application.
3. Colocated on the application servers themselves.

Without going through too much detail – each has its own limitations. In the first form, the application needs to know about all MySQL servers at any given point in time. With the third form, a large number of application servers, especially in the age of Kubernetes, where apps can simply recycle easily or be scaled up and down, backend connections can increase exponentially leading to issues.

In the second form, load balancing between a pool of ProxySQL servers is normally the challenge. Do you load balance the load balancers? While there are approaches like balancing from the application, similar to how the MongoDB drivers works, the …
