At our September 2016 New York City MySQL Meetup was a demonstration of how to implement role-based security in MySQL using Hexatier. In addition, several other important security features demonstrated included role based dynamic data masking down to a per column level and full statement auditing.
Thanks to Scott Unrick, Lead Database Administrator at Teladoc for the great presentation. Slides are available here.
At our June meetup, our guest speaker and Chief Evangelist from MariaDb Colin Charles gave a presentation on “Lessons from database failures”. Some of the details of his presentation included:
- Notable failures causing companies to go out of business
- varying backup commands and options
- Understanding a/semi/synchronous replication
- Replication topology management tools
- Proxy and sharding tools
- Security, SQL injections and encryption
At our August meetup, our guest Calvin Sun gave a presentation on life @ Twitter. Some of the details of his presentation included:
- Information on existing data and storage solutions in operation.
- MySQL 5.6 performance improvements over MySQL 5.5
- The short upgrade cadence, most servers are running 5.6.26.
- Various patches and optimizations developed by Twitter to run at scale.
- Cotton on Mesos
- Best practices
In this presentation on High Performance SQL and NoSQL to the New York Web Performance Meetup I use the simple analogy of applying the same techniques used in Web Performance Optimization (WPO) to your data path (SQL or NoSQL) performance.
This presentation provides examples for 5 of the most common WPO optimizations and how to apply this to your applications access to data:
- Gzip assets
- Make fewer HTTP requests
- Add expires headers
- Use a CDN
- Optimized Images
This presentation was recorded. A video link will be available at a later time.
Thanks to Grovo for hosting the event.
For those that are not familiar with MaxScale in the MySQL ecosystem, from the initial slides:
What is MaxScale?
The simple answer is a classical proxy that sits between the database clients and servers forwarding requests and responses.
The more detailed answer is a proxy platform for building highly tailored and configurable proxy implementations, that is database aware, and that is built with a pluggable architecture.

This presentation from the MySQL/NoSQL/Cloud Conference in Latin America provides my experiences of the most common problems managing MySQL Operations in general with customers, and a number of current problems experienced recently.
Many consider the ease of installation and use of MySQL as a selling point, however MySQL installation is not install and forget. It sounds simple, however there are many important decisions that have long lasting effects. The choice of version, choice of repo, choice of variant is just the beginning.
The appropriate configuration before any application uses the MySQL instance is also critical. Some decisions can lead to data integrity issues that can be difficult or impossible to correct without expensive rework. The decision regarding timezone management is one point discussed in detail.
However the greatest impact to the time and energy of MySQL operations is application development. The use of frameworks, the absence of knowledge of writing SQL, the lack or abuse of transactions all contribute to unnecessary complexity and stress in ensuring a performing and highly available MySQL infrastructure.
Day to day, tasks including testing and managing MySQL upgrades in a 24x7x365 environment, changing QEPs due to data distribution, complexities in point in time recovery with triggers, ROW base replication are all edge cases that have to be experienced to understand that MySQL operations is a detailed process to manage and support.
The outline of this presentation includes:
- What is Operations
- Operations Woes
- Day to day problems
- Other experiences
