It is good to see that MySQL is getting some improvements. It is a decent database, but they really need to fix replication and a number of other critical issues. Hopefully the different release cycle will help them target the issues better.
It's approaching the same feature-set as Microsoft SQL Server had over a decade ago, but still severely lacking in optimizations and performance for anything besides basic queries.
If you were to install an OS today, would you call Windows 98 "decent" and go for that, or ditch it for something modern?
And yet it runs several of the world's most popular websites.
That does however not mean I would tout those technologies as good general databases.
