How to contribute Dashboards to PMM

Have you already contributed to Percona’s open-source products or perhaps you wanted to try doing so?

The Anatomy of LuaJIT Tables and What's Special About Them

I don’t know about you, but I really like to get inside all sorts of systems. In this article, I’m going to tell you about the internals of Lua tables and special considerations for their use. Lua is my primary professional programming language, and if one wants to write good code, one needs at least to peek behind the curtain. If you are curious, follow me.

Unexpected slow ALTER TABLE in MySQL 5.7

Usually one would expect that ALTER TABLE with ALGORITHM=COPY will be slower than the default ALGORITHM=INPLACE. In this blog post we describe the case when this is not so.

Our Offer to Online Meetups and Community Leaders

Percona’s Community team organizes our speakers at in-person events around the world, such as Percona Live, Percona University, and events sponsored by other organizations. However, like everyone else around the world, all our plans are on hold due to the Coronavirus pandemic.

Deploying Tarantool Cartridge Applications with Zero Effort (Part 2)

Deploying Tarantool Cartridge Applications with Zero Effort (Part 1)

Tarantool is an open-source in-memory DB with a Lua application server on board. It’s best used for apps that require high performance and horizontal scaling. Out of the box we support horizontal scaling via the vshard module. There are quite a few things that you have to keep in mind when you work on your business logic, though. Not ideal.

Finding MySQL Scaling Problems Using perf

The thing I wish I’d learned while still a DBA is how to use perf. Conversely after moving to a developer role, getting access to real external client workloads to get a perf recording directly is rare. To bridge this gap, I hope to encourage a bit of perf usage to help DBAs report bugs/feature requests in more detail to MySQL developers, who can then serve your needs better.

How To Contribute to PMM Documentation

We’d love to see more contributions towards the development and improvement of Percona Monitoring and Management (PMM), one of Percona’s most valued projects. Like all of Percona’s software, PMM is free and open-source. An area where we’d dearly love to see some community provided enhancement is in its documentation. In future blog posts, we’ll provide some insight on how to contribute to our software but… the beauty of documentation is that it’s straightforward to maintain, and you don’t even have to be a programmer to be able to provide valuable corrections and enhancements. So it’s a great place to start. In this post, we set out how you might be able to contribute to this to make PMM even better than it is already!
