MariaDB: in-depth (hands on training in Seoul)Colin Charles
MariaDB: in-depth is training that was conducted for partners selling/deploying MariaDB in Seoul. Its a practical hands-on introduction that can be completed in 1-day.
MariaDB started life as a database to host the Maria storage engine in 2009. Not long after its inception, the MySQL community went through yet another change in ownership, and it was deemed that MariaDB will be a complete database branch developed to extend MySQL, but with constant merging of upstream changes.
The goal of the MariaDB project is to ensure that everyone is part of the community, including employees of the major steering companies. MariaDB also features enhanced features, some of which are common with the Percona Performance Server. Most importantly, MariaDB is a drop-in replacement and is completely backward compatible with MySQL. In 2010, MariaDB released 5.1 in February, and 5.2 in November – two major releases in a span of one calendar year is a feat that was achieved!
DBAs and developers alike will gain an introduction to MariaDB, what is different with MySQL, how to make use of the feature enhancements, and more.

- mariadb install step by step
- mariadb basic query
Differences between MariaDB 10.3 & MySQL 8.0Colin Charles
MySQL and MariaDB are becoming more divergent. Learn what is different from a high level. It is also a good idea to ensure that you use the correct database for the correct job.
Meet MariaDB 10.1 at the Bulgaria Web SummitColin Charles
Meet MariaDB 10.1 at the Bulgaria Web Summit, held in Sofia in February 2016. Learn all about MariaDB Server, and the new features like encryption, audit plugins, and more.
An introduction to MongoDB from an experienced MySQL user and developer. There are differences and we go thru the What/Why/Who/Where of MongoDB, the "similarities" to the MySQL world like storage engines, how replication is a little more interesting with built-in sharding and automatic failover, backups, monitoring, DBaaS, going to production and finding out more resources.
Tuning Linux for your database FLOSSUK 2016Colin Charles
Some best practices about tuning Linux for your database workloads. The focus is not just on MySQL or MariaDB Server but also on understanding the OS from hardware/cloud, I/O, filesystems, memory, CPU, network, and resources.
MySQL is a unique adult (now 21 years old) in many ways. It supports plugins. It supports storage engines. It is also owned by Oracle, thus birthing two branches of the popular opensource database: Percona Server and MariaDB Server. It also once spawned a fork: Drizzle. Lately a consortium of web scale users (think a chunk of the top 10 sites out there) have spawned WebScaleSQL.
You're a busy DBA having to maintain a mix of this. Or you're a CIO planning to choose one branch. How do you go about picking? Supporting multiple databases? Find out more in this talk. Also covered is a deep-dive into what feature differences exist between MySQL/Percona Server/MariaDB/WebScaleSQL, how distributions package the various databases differently. Within the hour, you'll be informed about the past, the present, and hopefully be knowledgeable enough to know what to pick in the future.
Note, there will also be coverage of the various trees around WebScaleSQL, like the Facebook tree, the Alibaba tree as well as the Twitter tree.
This is my third iteration of the talk presented in Tokyo, Japan - first was at a keynote at rootconf.in in April 2016, then at the MySQL meetup in New York, and now for dbtechshowcase. The focus is on database failures of the past, and how modern MySQL / MariaDB Server technologies could have helped them avoid such failure. The focus is on backups and verification, replication and failover, and security and encryption.
Today you can use hosted MySQL/MariaDB/Percona Server in several "cloud providers" in what is considered using it as a service, a database as a service (DBaaS). You can also use hosted PostgreSQL and MongoDB thru various service providers. Learn the differences, the access methods, and the level of control you have for the various public cloud offerings:
- Amazon RDS for MySQL and PostgreSQL
- Google Cloud SQL
- Rackspace OpenStack DBaaS
- The likes of compose.io, MongoLab and Rackspace's offerings around MongoDB
The administration tools and ideologies behind it are completely different, and you are in a "locked-down" environment. Some considerations include:
* Different backup strategies
* Planning for multiple data centres for availability
* Where do you host your application?
* How do you get the most performance out of the solution?
* What does this all cost?
Growth topics include:
* How do you move from one DBaaS to another?
* How do you move all this from DBaaS to your own hosted platform?
Questions like this will be demystified in the talk. This talk will benefit experienced database administrators (DBAs) who now also have to deal with cloud deployments as well as application developers in startups that have to rely on "managed services" without the ability of a DBA.
Better encryption & security with MariaDB 10.1 & MySQL 5.7Colin Charles
Talking about the improvements in MariaDB on MySQL security and encryption features that are so important in today's data landscape. Presented http://www.meetup.com/EffectiveMySQL/events/224828891/
MySQL features missing in MariaDB ServerColin Charles
MySQL features missing in MariaDB Server. Here's an overview from the New York developer's Unconference in February 2018. This is primarily aimed at the developers, to decide what goes into MariaDB 10.4, as opposed to users.
High level comparisons are made between MySQL 5.6/5.7 with of course MySQL 8.0 as well. Here's to ensuring MariaDB Server 10/310.4 has more "Drop-in" compatibility.
MariaDB Server Compatibility with MySQLColin Charles
At the MariaDB Server Developer's meeting in Amsterdam, Oct 8 2016. This was the deck to talk about what MariaDB Server 10.1/10.2 might be missing from MySQL versions up to 5.7. The focus is on compatibility of MariaDB Server with MySQL.
Best practices for MySQL/MariaDB Server/Percona Server High AvailabilityColin Charles
Best practices for MySQL/MariaDB Server/Percona Server High Availability - presented at Percona Live Amsterdam 2016. The focus is on picking the right High Availability solution, discussing replication, handling failure (yes, you can achieve a quick automatic failover), proxies (there are plenty), HA in the cloud/geographical redundancy, sharding solutions, how newer versions of MySQL help you, and what to watch for next.
Having spent more than the last decade being the main point of contact for distributions shipping MySQL, then MariaDB Server, it's clear that working with distributions have many challenges. Licensing changes (when MySQL moved the client libraries from LGPL to GPL with a FOSS Exception), ABI changes, speed (or lack thereof) of distribution releases/freezes, supporting the software throughout the lifespan of the distribution, specific bugs due to platforms, and a lot more will be discussed in this talk. Let's not forget the politics. How do we decide "tiers" of importance for distributions? As a bonus, there will be a focus on how much effort it took to "replace" MySQL with MariaDB.
Benefits: if you're making a distribution, this is the point of view of the upstream package makers. Why are distribution statistics important to us? Do we monitor your bugs system or do you have a better escalation to us? How do we test to make sure things are going well before release. This and more will be spoken about.
As an upstream project (package), we love nothing more than being available everywhere. But time and energy goes into making this is so as there are quirks in every distribution.
MariaDB Server 10.3 is a culmination of features from MariaDB Server 10.2+10.1+10.0+5.5+5.3+5.2+5.1 as well as a base branch from MySQL 5.5 and backports from MySQL 5.6/5.7. It has many new features, like a GA-ready sharding engine (SPIDER), MyRocks, as well as some Oracle compatibility, system versioned tables and a whole lot more.

The MariaDB update for 2011 from Michael Widenius of Monty Program. This was a keynote given on Wednesday 13 April 2011 at the O'Reilly MySQL Conference & Expo 2011.
A talk given to the New York CakePHP usergroup, discussing the specifics of changes within the CakePHP 2.0 feature set, motivations for those changes, and upcoming changes as development continues.
This presentation explains the major differences between SQL and NoSQL databases in terms of Scalability, Flexibility and Performance. It also talks about MongoDB which is a document-based NoSQL database and explains the database strutre for my mouse-human research classifier project.
CakePHP 3 comes with a new ORM. This talk starts with a short history of how this library came to be and then walk through a series of examples from beginner to advanced for using the Querying features of the ORM.
The relational database has been the dominant database model for many years. However, a new model called NoSQL is gaining significant attention. NoSQL DBs are non-relational data stores that have been employed in various scenarios, where traditional RDBMS features matter less, and the improved performance of storing or retrieving relatively simple data sets matters most. The relational and the NoSQL database model are each good for specific applications. Depending on the problem to solve, a NoSQL or a relational model can be advantageous. In this session we present some typical use cases and how they can be solved with both NoSQL and the RDMBS databases. Will there be clear a winner or is there room for both NoSQL and RDMBS in the future?

Node.js vs Play Framework (with Japanese subtitles)Yevgeniy Brikman
Video: http://www.nicovideo.jp/watch/1410857293
Here's the showdown you've been waiting for: Node.js vs Play Framework. Both are popular open source web frameworks that are built for developer productivity, asynchronous I/O, and the real time web. But which one is easier to learn, test, deploy, debug, and scale? Should you pick Javascript or Scala? The Google v8 engine or the JVM? NPM or Ivy? Grunt or SBT? Two frameworks enter, one framework leaves.
This version of the presentation has Japanese subtitles. For the English only version, see http://www.slideshare.net/brikis98/nodejs-vs-play-framework
NoSQL databases are currently used in several applications scenarios in contrast to Relations Databases. Several type of Databases there exist. In this presentation we compare Key Value, Column Oriented, Document Oriented and Graph Databases. Using a simple case study there are evaluated pros and cons of the NoSQL databases taken into account.
OSDC 2018 | Scaling & High Availability MySQL learnings from the past decade+...NETWAYS
The MySQL world is full of tradeoffs and choosing a High Availability (HA) solution is no exception. This session aims to look at all of the alternatives in an unbiased nature. While the landscape will be covered, including but not limited to MySQL replication, MHA, DRBD, Galera Cluster, etc. the focus of the talk will be what is recommended for today, and what to look out for. Thus, this will include extensive deep-dive coverage of ProxySQL, semi-sync replication, Orchestrator, MySQL Router, and Galera Cluster variants like Percona XtraDB Cluster and MariaDB Galera Cluster. I will also touch on group replication.
Learn how we do this for our nearly 4000+ customers!
[db tech showcase Tokyo 2014] B15: Scalability with MariaDB and MaxScale by ...Insight Technology, Inc.

MariaDB - the "new" MySQL is 5 years old and everywhere (LinuxCon Europe 2015)Colin Charles
MariaDB is like the "new" MySQL, and its available everywhere. This talk was given at LinuxCon Europe in Dublin in October 2015. Learn about all the new features, considering the release was just around the corner. Changes in replication are also very interesting
OSDC 2017 | Lessons from database failures by Colin CharlesNETWAYS
Lets learn from MySQL failures at scale, because we tie in the topic of High Availability, in where people are thinking about geographical redundancy, and even things like automatic failover. In the talk there will be case study material, e.g. where automatic failure caused a site to go offline, where a social network started of with not using fully automated failovers but evolved, etc. How is the MySQL world making things better, for example by allowing you to use semi-synchronous replication to run fully scalable services. The talk starts off with an even almost stupid example of how a business died due to incorrect MySQL backup procedures. It will go on to talk about security and encryption at rest as well. So a mix of problems from the field, big “fail whales”, and how you should avoid them by properly architecting solutions.
Best practices for MySQL High AvailabilityColin Charles
The MariaDB/MySQL world is full of tradeoffs, and choosing a high availability (HA) solution is no exception. This session aims to look at all the alternatives in an unbiased way. Preference is of course only given to open source solutions.
How do you choose between: asynchronous/semi-synchronous/synchronous replication, MHA (MySQL high availability tools), DRBD, Tungsten Replicator, or Galera Cluster? Do you integrate Pacemaker and Heartbeat like Percona Replication Manager? The cloud brings even more fun, especially if you are dealing with a hybrid cloud and must think about geographical redundancy.
What about newer solutions like using Consul for MySQL HA?
When you’ve decided on your solution, how do you provision and monitor these solutions?
This and more will be covered in a walkthrough of MySQL HA options and when to apply them.
Failure happens, and we can learn from it. We need to think about backups, but also verification of them. We should definitely make use of replication and think about automatic failover. And security is key, but don't forget that encryption is now available in MySQL, Percona Server and MariaDB Server.
MySQL Ecosystem in 2023 - FOSSASIA'23 - Alkin.pptx.pdfAlkin Tezuysal
MySQL is still hot, with Percona XtraDB Cluster (PXC) and MariaDB Server. Welcome back post-pandemic to see what is on offer in the current ecosystem.
Did you know that Amazon RDS now uses semi-sync replication rather than DRBD for multi-AZ deployments? Did you know that Galera Cluster for MySQL 8 is much more efficient with CLONE SST rather than using the xtrabackup method for SST? Did you know that Percona Server continues to extend MyRocks? Did you know that MariaDB Server has more Oracle syntax compatibility? This and more will be covered in the session, while short and quick, should leave you wandering to discover new features for production.
Presented at the MySQL Chicago Meetup in August 2016. The focus of the talk is on backups and verification, replication and failover, as well as security and encryption.
OSDC 2016 - Tuning Linux for your Database by Colin CharlesNETWAYS
Many operations folk know that performance varies depending on using one of the many Linux filesystems like EXT4 or XFS. They also know of the schedulers available, they see the OOM killer coming and more. However, appropriate configuration is necessary when you're running your databases at scale.
Learn best practices for Linux performance tuning for MariaDB/MySQL (where MyISAM uses the operating system cache, and InnoDB maintains its own aggressive buffer pool), as well as PostgreSQL and MongoDB (more dependent on the operating system). Topics that will be covered include: filesystems, swap and memory management, I/O scheduler settings, using and understanding the tools available (like iostat/vmstat/etc), practical kernel configuration, profiling your database, and using RAID and LVM.
There is a focus on bare metal as well as configuring your cloud instances in.
Learn from practical examples from the trenches.
Introduction to TokuDB v7.5 and Read Free ReplicationTim Callaghan

Percona ServerをMySQL 5.6と5.7用に作るエンジニアリング(そしてMongoDBのヒント)Colin Charles
Engineering that goes into making Percona Server for MySQL 5.6 & 5.7 different (and a hint of MongoDB) for dbtechshowcase 2017 - the slides also have some Japanese in it. This should help a Japanese audience to read it. If there are questions due to poor translation, do not hesitate to drop me an email (byte@bytebot.net) or tweet: @bytebot
Databases require capacity planning (and to those coming from traditional RDBMS solutions, this can be thought of as a sizing guide). Capacity planning prevents resource exhaustion. Capacity planning can be hard. This talk has a heavier leaning on MySQL, but the concepts and addendum will help with any other data store.
The Proxy Wars - MySQL Router, ProxySQL, MariaDB MaxScaleColin Charles
As proxies (and database routers) go, the first one I ever used was the now deprecated MySQL Proxy. Since then, I've managed to use MariaDB MaxScale quite a bit (including its fork AirBnB MaxScale), played around with ProxySQL in recent time, and also started taking a look at MySQL Router. In this quick 20-minute overview, we'll discuss why these three exist, a feature comparison, and reasons when to use the right tool for the job.
Lessons from {distributed,remote,virtual} communities and companiesColin Charles

Securing your MySQL / MariaDB Server dataColin Charles
Co-presented alongside Ronald Bradford, this covers MySQL, Percona Server, and MariaDB Server (since the latter occasionally can be different enough). Go thru insecure practices, focus on communication security, connection security, data security, user accounts and server access security.
This was a short 25 minute talk, but we go into a bit of a history of MySQL, how the branches and forks appeared, what's sticking around today (branch? Percona Server. Fork? MariaDB Server). What should you use? Think about what you need today and what the roadmap holds.
Meet MariaDB Server 10.1 London MySQL meetup December 2015Colin Charles

Do you wonder how to contribute to MariaDB? Have you considered writing a plugin? MariaDB ships many plugins (over a hundred) and you could also be one of them. Find out what they do, how to use them, and so forth. A lightning talk given for the MySQL NL User Group meetup in Amsterdam.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
