MariaDB Server
MariaDB Server's new release model
<p>As was announced in December 2021 https://mariadb.org/new-innovation-release-model/, MariaDB Server now has a new release model, with more frequent major releases. MariaDB Server 10.7 is the first release following this model.</p>
<p>Some of these releases will have 1 year support cycles, while others will be supported long term just like before. In this talk, I will present the pros and cons of this new release model, what it means for the MariaDB Server community, its users and also its developers. This will also give the community a chance to better understand the changes and give us feedback and ultimately ensure MariaDB Server properly serves its purpose of being a true Open Source Database.</p>

<p>At the time of writing, MariaDB 10.7 is in RC, and the MariaDB 10.8 preview releases are imminent. The new release model means new features no longer have to wait a year between major releases before seeing the light of day, and the initiative of separate preview releases for each major feature eases testing and reduces instability.</p> <p>This presentation covers some of the major new features being unveiled in MariaDB 10.7 and 10.8.</p>

<p>Current MariaDB Server GA versions are formally not supported on macOS 10.x and 11.y. But it;s relatively easy to set up the environment and build it from current 10.2 - 10.7 GitHub sources, with few minor issues to resolve in the process depending on maxOS and major server version used. This talk is a summary of my related experience, with a quick review of related fixed and open bugs, as well as some unique features like DTrace support that one may benefit from on macOS.</p>

<p>MariaDB 10.8 is getting improved histograms, called JSON_HB. This talk will cover - what the new histograms are, - what are the advantages over the old histograms, - how do they compare to histograms in MySQL 8.</p> <p>At the end of the talk, I'll cover a closely related topic of usage of the histogram data in the query optimizer: - why this is hard, - what are known limitations and their workarounds - what MariaDB team is doing to improve this.</p>

<p>The persistent circular buffer (the <code>ib_logfile0</code>) is the fundament of the persistent InnoDB buffer pool.</p> <p>Over the years, the log file format has been changed in MariaDB Server to improve the performance. A well-designed file format imposes minimal write amplification and is easy to parse.</p>

<p>The MariaDB optimizer has its roots in the original MySQL optimizer. Being a long standing project, it has inherited a number of quirks and features that -at the time of coding- made sense. The datasets had different sizes 10-20 years ago and the cost model is not always accurate for current workloads.</p> <p>Thus, there is now an ongoing effort to significantly improve the calculations that the MariaDB Optimizer is doing. With the addition of JSON Histograms, the range optimizer is one of ...
