As you may have noticed, MySQL 8.0.16 has been released today !

One of the major long expected feature is the support of CHECK contraints .

My colleague, Dave Stokes, already posted an article explaining how this works.

In this post, I wanted to show how we could take advantage of this new feature to validate JSON values.

Let’s take the following example:

So we have a collection of documents representing rates from a user on some episodes. Now, I expect that the value for the rating should be between 0 and …

We store data with the intention to use it: search, retrieve, group, sort, etc. To perform these actions effectively, MySQL storage engines index data and communicate statistics with the Optimizer when it compiles a query execution plan. This approach works perfectly well unless your data distribution is uneven.

Last year I worked on several tickets where data followed …

Sysbench has long been established as the de facto standard when it comes to benchmarking MySQL performance. Percona relies on it daily, and even Oracle uses it when blogging about new features in MySQL 8. Sysbench comes with several pre-defined benchmarking tests. These tests are written in an easy-to-understand scripting language called Lua. Some of these tests are called: oltp_read_write, oltp_point_select, tpcc, oltp_insert. There are over ten such scripts to emulate various behaviors found in standard OLTP applications.

But what if your application does not fit the pattern of traditional OLTP? How can you continue to utilize the power of load-testing, benchmarking, …

We are pleased to announce the launch of PMM 2.0.0-alpha1, Percona’s first Alpha release of our long-awaited PMM 2 project! We focused exclusively on MySQL support in our first Alpha (because we wanted to show progress sooner rather than later), and you’ll find updated MySQL dashboards along with enhancements to Query Analytics. We’ve also added better visibility regarding which services are registered with PMM Server, the client-side addition of a new agent called pmm-agent, and finally PMM Server is now exposing an API!
