Authentication in MariaDB 10.4 — Understanding the Changes

MariaDB Server 10.4 came with a whole lot of Security related changes. Some of them are merely optimizations (like MDEV-15649), some improve existing features to be more robust (MDEV-15473, MDEV-7598) or convenient (MDEV-12835, MDEV-16266). Some are MySQL compatibility features, requested by our users (MDEV-7597, MDEV-13095). But the first thing any MariaDB Server user, whether an […]

On References to MariaDB and MariaDB Bugs (MDEVs) in MySQL Bug Reports

Recently I noted that some of my comments to public MySQL bug reports got hidden by somebody from Oracle with privileges to do so. I was not able to find out who did that and when, as this information is not communicated to bug subscribers (this may change if my feature requests, Bug #94807 - "Subscriber should be notified when comment is made private", is eventually implemented).

When it happened for the first time I thought it was probably non-intentional. When it happened for a second time I complained with a tweet that got few likes and zero comments. Recently this happened again and yet another tweet had not got much attention, but at least I've got a comment via …

Chose right SST method MariaDB Cluster 10.2

                In this blog post, I am going to explain an interesting issue which I faced in one of our client project . Few weeks back , I got an requirement from our support client to construct a new MariaDB Galera Cluster ( 10.2.21 ) and an async slave with GTID. The Complete requirement is as below.

  • Need to construct the Galera cluster with 37 GB of data ( Using a given MySQL dump file )
  • Have to configure an asynchronous slave under the 3 node Galera cluster
  • The asynchronous slave was proposed with GTID to ease master node switchover.

So, as per the requirement the architecture will be,

London Open Source Database Community Meetup

I strongly believe in the community.

Communities are the real strength of open source. Not just the theoretical ability to study, modify and share code – but the fact that other people out there are doing these things. Creating a base of knowledge and a network of relations.These can become work relationships, valuable discussions, open source tools, or even friendships.

That is why, when I heard that several people from the Percona support team will soon be in London, I badly wanted to organise an event.

Actually, there was an interesting coincidence. When I asked Sveta Smirnova if anyone from Percona lives in London, I already knew I wanted to organise an event with this new meetup group I’ve started: …

MariaDB OpenWorks was an ocean of Galera Cluster activity

MariaDB OpenWorks happened February 25-27 2019 in New York City, and it was filled with a lot of activity.

The keynote by Michael Howard is an interesting watch, one with many quoted articles especially around “strip-mining open source technologies and companies,” and “abusing the license and privilege, and not giving back to the community.” Many articles were written about this topic, and it is clear that open source has arrived considering all the success around the IBM acquisition of Red Hat, the Elastic IPO, the Microsoft acquisition of GitHub, the SalesForce acquisition fo MuleSoft and the MongoDB IPO.

Seppo Jaakola talked about …

Fun with Bugs #81 - On MySQL Bug Reports I am Subscribed to, Part XVII

Two weeks passed since my previous review of public MySQL bug reports I consider interesting enough to subscribe to them. Over this period I picked up a dozen or so new public bug reports that I'd like to briefly review today.

Here is my recent subscriptions list, starting from the oldest bug reports:

  • Bug #94431 - "Can't upgrade from 5.7 to 8.0 if any database have a hyphen in their name". It seems one actually needs a database like that created in MySQL 5.6 with at least one InnoDB table having FULLTEXT index to hit the problem. Great finding by Phil Murray. Note that after several unsuccessful attempts by others the bug was eventually reproduced and verified by …
