Most of us are lucky that software bugs are a small part of our lives. The ‘things just work’ attitude works for most situations, but occasionally something appears that may seem trivial at first glance may be catastrophic.

A bug appeared in MySQL’s recently released 8.0.32 that really caught my attention. This is a prime example of how a minor bug could have a significant impact on your life and a detrimental impact on your company or project.

The title Wrong result for AVG() OVER(ROWS BETWEEN 1 FOLLOWING AND UNBOUNDED FOLLOWING) is the first thing that caught my eye. A lot of developers heavily use the AVG() function. My first thought was, ‘ut-oh, AVG() being broken is a terrible thing,’ but then I realized it was thankfully not that drastic.

The OVER() clause indicates this is a problem in a Window Function. And odds are, if you are using OVER() for …

The relationship between the binary logging formats and the terminology used during replication is as follows:

When using statement-based binary logging, the source writes SQL statements to the binary log. Replication of the source to the replica is performed by executing these SQL statements on the replica. This is known as statement-based replication (SBR), and it …
