One of the great values of a Percona Support contract is that we provide bug fixes for covered software, and not just support in terms of advice on how to use it. This is the skill which is most likely missing from in-house for most customers, as it requires a team with code knowledge to build and test infrastructure – something only a few companies can afford to invest in.

There is a lot of misunderstanding about bugs. What is a bug? What is a feature? What is a repeatable bug? How will Percona troubleshoot the bug? In this post I will answer some of the questions about this.

Bugs vs. Features ⎼ One thing a lot of people have a hard time understanding is the difference between a bug and a feature, or when software was designed to work a certain way which might be unwelcome. There is a gray line …

For those PCT users who forget to regularly check query performance, you can now get server query reports delivered to your email daily or weekly. The report contains a digest of the most critical performance information related to a particular MySQL instance, enabling you to act on any recent issues. There are convenient links that open the corresponding view of the PCT Query Analytics module.

Server summary snapshot

The report also provides a list of ten slowest queries and ten queries with the highest load during the period. It is important to compare these lists, because some of the slowest queries may occur only several times during the period (so they probably do not overload the server), while seemingly quick queries may run millions of times and put a lot of unnecessary overhead, which you could …
