Geek code for LSM trees

This is a link to slides from my 5-minute talk at the CIDR 2019 Gong Show. The slides are a brief overview of the geek code for LSM trees. If you click on the settings icon in the slide show you can view the speaker notes which have links to blog posts that have more details. I also pasted the links below. Given time I might add to this post, but most of the content is in my past blog posts. Regardless I think there is more to be discovered about performant, efficient and manageable LSM trees.

The key points are there are more compaction algorithms to discover, we need to make it easier to describe them and compaction is a property of a level, not of the LSM tree. …

It turned out that active development switched to its port in Go called dbdeployer. You can find detailed information about dbdeployer and reasons behind developing it provided by its author, Giuseppe Maxia, here and there. See also this post at Percona blog for some quick review of its main features. One of the points of …

Customizing Per-Process Metrics in PMM

If you have set up per-process metrics in Percona Monitoring and Management, you may have found yourself in need of tuning it further to not only group processes together, but to display some of them in isolation. In this blogpost we will explore how to modify the rules for grouping processes, so that you can make the most out of this awesome PMM integration.

Let’s say you have followed the link above on how to set up the per-process metrics integration on PMM, and you have imported the dashboard to show these metrics. You will see something like the following:

This is an internal testing server we use, in which you can see a high number of VBoxHeadless (29) and mysqld (99) processes running. All the metrics in the dashboard will be grouped by the name of the command used. But, what if we …

Understanding Status of MariaDB Server JIRA Issues

In my previous blog post on MariaDB's JIRA for MySQL users who are familiar with MySQL bugs database (but may be new to JIRA) I've presented some details about statuses that JIRA issues may have. There is no one to one correspondence with MySQL bug's statuses that I once described in details here. In case of MariaDB Server bugs ("JIRA issues") one may have to check not only "Status" field, but also "Resolution" filed and even "Labels" field to quickly understand what is the real status and what MariaDB engineers decided or are waiting for. So, I think some additional clarifications may help MySQL users who check …
