Windowing functions are way to group rows of data for analysis. This provides a 'window' to look at only the relevant data only.  Plus there are about a dozen supporting functions to take advantage of all this. There is some carry over logically from the aggregate (or group by) functions but they open up some easy ways to dig statistically into your data.

Now for a contrived example.

mysql> Select row_number() over w as '#', 
       Name, Continent, Population, 
       sum(Population) over w as 'Pop' 
       from country where continent='South America' 
window w as (partition by Continent Order by Continent);

The reason is simple: with the help of virtual columns, we can create fine-grained indexes that can significantly increase query performance. I’m going to show you some tricks that can potentially fix slow reporting queries with GROUP BY and ORDER BY.

The Problem

Recently I was working with a customer who was struggling with this query:

SELECT
CONCAT(verb, ' - …

via GIPHY I was at a dinner party recently, and talking with some colleagues. I had worked with them years back on Oracle systems. One colleague Maria said she really enjoyed my newsletter.

“MySQL master/slave setup was just too fragile and needed regular work to fix each time the slave got out of sync. Now with Galera we’ve found that even if we take a node offline for a while, it re-syncs automatically and without intervention.”

“The big plus is that all nodes have exact the same information, and no node is running for even a fraction of a second behind. This will also mean that no information will be lost!”
