Feed: Planet MySQL; Author: Dimitri Kravtchuk; Few weeks ago with a big curiosity I was reading several articles published by Percona about TPCC Benchmark results and MySQL 8.0 "checkpointing" issues.. Unfortunately, in these articles there was no any explanation nor any tentative to understand what is going on, an probably at least try and validate some "first coming in mind" tuning / troubleshooting options.. (And even no any try to show in action so often advertised PMM, and see on what it'll point ?).. All in all, in the following article I'll try to feel up the "white holes" left ... Read More

Feed: Planet MySQL; Author: Valeriy Kravchuk; In my previous post in this series I've commented on some interesting MySQL bug reports that were added during the second half of April. Time to move on to bugs reported in May, 2020, as we are quickly approaching MySQL Bug #100000 soon and I want to write a separate post for this great achievement :) Here is the list:Bug #99432 - "Improving memory barrier during rseg allocation". Nice contribution by my former colleague in Percona, Krunal Bauskar, who now works on making MySQL better for ARM processors. According to his findings, the use ... Read More

Feed: Actian. Author: Jack Mardack. It feels like only yesterday that “Machine Learning” and “Artificial Intelligence” were equated with science fiction by most regular folks outside of tech. As a movie-going culture, we have a long history of associating these concepts with self-aware robots or rogue computer programs that could escape the laboratories where they were created and threaten all humanity. But in 2020, ML and AI have been considerably demystified. And yet, even if it seems less likely now that the Singularity will be triggered by the reckless ambition of some tech startup, consumers have new reasons to be concerned. Yes, ML and AI are going mainstream, and it’s not just disruption-minded startups that are leveraging these technologies. Enterprises in a wide range of established industries are finding solid business reasons ... Read More

Reliability and response time are always pressing concerns for internet services. We’ve known for a long time that people on desktop or laptop computers have scant patience for slow websites, and the growing move to mobile devices makes the demands on internet services even worse. O'Reilly Media and Oracle Dyn teamed up this year to survey network operators about where their resilience problems lie, what they're doing to avoid these ... Read More

Feed: Planet MySQL; Author: Valeriy Kravchuk; I've decided to stop reviewing MySQL Release Notes in this series, but it does not mean that I am not interested in MySQL bugs any more. At the moment I am subscribed to 91 active MySQL bugs reported by other MySQL users, and in this blog post I am going to present 15 of them, the most recently reported ones. I'd really want to see them fixed or at least properly processed as soon as possible.In some cases I am going to add my speculations on how the bug had better be handled, or ... Read More

This is a "Howto" kind of post, and some speculations and historical references aside, it will show you how to build MariaDB ColumnStore (current version 1.0.9) from GitHub source, how to install and configure it for basic usage, as well as how to resolve some minor problems you may get in the process. Keep reading and eventually you'll get the real Howto below :) * * * I try not to care about any software issues besides good old MySQL, InnoDB storage engine internals, query optimization and some MyRocks or a little bit of ...

Feed: Planet MySQL. Author: Valeriy Kravchuk. Back in January 2014, some time after many nice people kindly asked me to shut up stop writing about MySQL bugs on Facebook several times per day, I decided to start reading the fine MySQL Manual more carefully than before and report not only typos there, but also any topic or detail not properly explained. Usually these reports, tagged as "missing manual", were the result of careful study of the documentation based on real user question or customer issue. So, most of these reports came from real life, and missing information badly affected poor ... Read More
