I was looking at the latest MySQL versions, and I happened to notice that there has been a great increment in the number of metadata tables, both in the information_schema and performance_schema databases. So I made a simple count of both schemas in the various versions, and draw a graph. The advance looks straightforward.

The difference between 5.0 and 5.6 is staggering. We came from 17 to 71 metadata total tables. A stacked bar chart helps visualize the changes.

I noticed, BTW, that MySQL 5.0.92, which is not in active support, was released without the binaries for Mac OSX. If this kind of edition is limited to the versions in extended support, that's fine with me. I hope the habit does not contaminate the regular builds.![]()
