MySQL Contributions status

This post is an update to the status of various MySQL bugs (some with patches) that I’ve filed over the past couple of years (or that people around me have). I’m not looking at POWER specific ones, as there are these too, but each of these bugs here deal with general correctness of the code base.

Firstly, let’s look at some points I’ve raised:

  • Incorrect locking for global_query_id (bug #72544)
    Raised on May 5th, 2014 on the internals list. As of today, no action (apart from Dimitri verifying the bug back in May 2014). There continues to be locking that perhaps only works by accident around query IDs.Soon, this bug will be two years old.
  • Endian code based on CPU type rather than endian define (bug …

High availability with asynchronous replication… and transparent R/W split

In this post, the first one of a Maxscale series, I describe how to use MariaDB’s MaxScale and MySQL-utilities with MySQL Asynchronous replication.

When we talk about high availability with asynchronous replication, we always think about MHA or PRM. But if we want to transparently use the slave(s) for READs, what can we use ?

Description:

  • Three MySQL servers, but one has very limited resources and will …

Questions about MariaDB’s bug system

MariaDB recently announced the migration of the JIRA bug tracking system from the current Atlassian-hosted instance to a self-hosted installation to be found at jira.mariadb.org.    This likely isn’t a big deal to the community, and MariaDB is being very proactive in coordinating this change in the community – but it’s an opportunity for me to ask a few questions regarding MariaDB’s JIRA usage to which I can’t find answers.  I certainly welcome answers, feedback or clarification from MariaDB staff.

Before getting started, I should say that I appreciate MariaDB – the product, the company, the staff and the foundation.  MariaDB/SkySQL/Monty Programs serve a unique and useful purpose for community, users and staff who prefer …

Loading JSON into MariaDB or even MySQL - mysqljsonimport 2.0 is available

It was a long time since I updated mysqljsonimport or mysqljsonexport and I had a few things I wanted to do with them. This release is significant enough for me to bump it up to 2.0, and the same is in the works for mysqljsonexport. The one big thing that is now implemented is reasonably advanced support for MariaDB Dynamic Columns, and it is actually pretty flexible, allowing you to load a nested JSON object into a MariaDB Dynamic Column. But don't worry, it will still link and run with MySQL if that is what you want to do (but then you will not have the dynamic column features, for obvious reasons),

Download from Sourceforge as usual (yes, I know I am oldfashioned and that I should have put it on github). Also as usual is the documentation in pdf format that is also downloadable separately.

MySQL Auditing with MariaDB Auditing Plugin

This blog will address how the MariaDB Auditing Plugin can help monitor database activity to help with security, accountability and troubleshooting.

Why Audit Your Databases?

Auditing is an essential task for monitoring your database environment. By auditing your database, you can achieve accountability for actions taken or content accessed within your environment. You will also deter users (or others) from inappropriate actions.

If there is any bad behavior, you can investigate suspicious activity. For example, if a user is deleting data from tables, the admins could audit all connections to the database and all deletions of rows. You can also use auditing to notify admins when an unauthorized user manipulates or deletes data or that a user has more privileges than expected.

Auditing Plugins Available for MySQL

As Sergei Glushchenko said in a …

MariaDB JIRA is moving

The MariaDB JIRA instance that currently is in use for project and issue tracking will change. The current instance is hosted in Atlassian’s cloud and it has worked well, but we have hit the maximum user limit of 2000 users. It’s fantastic to see how many of you actually report bugs and other issues in the MariaDB […]

MariaDB and Native JSON support ?

A question raised by my previous post is : What about MariaDB and native JSON support ? In my previous post I mentioned the possibility to use the MariaDB CONNECT storage Engine to store and access JSON content in normal text field. Of course having a native JSON datatype brings more value. It introduces JSON [...]

FOSDEM 2016 – See you in Brussels

Over the weekend I read in the FT (paywall): Is Brussels safe? Ring a local resident to find out. I’m sure it will be fine, and you will want to be there for FOSDEM, happening 30-31 January 2016. 

There is the excellent one day track, that is the MySQL & Friends Devroom (site). Talks hail from Oracle, MariaDB Corporation, Percona and more. We don’t have a booth this year, but we do have amazingly good content on Saturday. I’m happy to have been part of the committee that chose the talks, but you know that this is a labour of love put on by Frédéric Descamps, Liz van Dijk, Dimitri Vanoverbeke, and Kenny Gryp. …

SCALE14x – lots of MySQL content there

One of my favourite events run by a grassroots organisation is SCALE, and they are now doing their 14th edition, SCALE14x. If you’re into opensource software as well as all things open, this is the place to be from January 21-24 2016. It is at a new location in Pasadena (so not quite next to LAX as it was previously), but this is due to growth — so kudos to the team.

From MariaDB Corporation you get to see Max Mether (Scaling MySQL & MariaDB – I’m extremely interested in seeing what he has to say and will likely blog the session) and me (The MySQL Server Ecosystem in …
