Percona Live Frankfurt 2018 – Event Recap & Our Sessions

Forrest Lymburner


Severalnines was pleased to yet again sponsor Percona Live Europe which was held this year in Frankfurt, Germany. Thanks to the Percona Team for having us and the great organisation.

At the Conference

Severalnines team members flew in from around the world to show off the latest edition of ClusterControl in the exhibit hall and present five sessions (see below).

On our Twitter feed we live tweeted both of the keynote sessions to help keep those who weren’t able to attend up-to-speed on the latest happenings in the open source database world.

Our Sessions

Members of the Severalnines Team presented five sessions in total at the event about MySQL, MariaDB & MongoDB, each of which showcased ClusterControl and how it delivers on those topics.

Disaster Recovery Planning for MySQL & MariaDB

Presented by: Bart Oles – Severalnines AB

Session Details: Organizations need an appropriate disaster recovery plan to mitigate the impact of downtime. But how much should a business invest? Designing a highly available system comes at a cost, and not all businesses and indeed not all applications need five 9’s availability. We will explain fundamental disaster recovery concepts and walk you through the relevant options from the MySQL & MariaDB ecosystem to meet different tiers of disaster recovery requirements, and demonstrate how to automate an appropriate disaster recovery plan.

MariaDB Performance Tuning Crash Course

Presented by: Krzysztof Ksiazek – Severalnines AB

Session Details: So, you are a developer or sysadmin and showed some abilities in dealing with databases issues. And now, you have been elected to the role of DBA. And as you start managing the databases, you wonder

  • How do I tune them to make best use of the hardware?
  • How do I optimize the Operating System?
  • How do I best configure MySQL or MariaDB for a specific database workload?

If you’re asking yourself the following questions when it comes to optimally running your MySQL or MariaDB databases, then this talk is for you!

We will discuss some of the settings that are most often tweaked and which can bring you significant improvement in the performance of your MySQL or MariaDB database. We will also cover some of the variables which are frequently modified even though they should not.

Performance tuning is not easy, especially if you’re not an experienced DBA, but you can go a surprisingly long way with a few basic guidelines.

Performance Tuning Cheat Sheet for MongoDB

Presented by: Bart Oles – Severalnines AB

Session Details: Database performance affects organizational performance, and we tend to look for quick fixes when under stress. But how can we better understand our database workload and factors that may cause harm to it? What are the limitations in MongoDB that could potentially impact cluster performance?

In this talk, we will show you how to identify the factors that limit database performance. We will start with the free MongoDB Cloud monitoring tools. Then we will move on to log files and queries. To be able to achieve optimal use of hardware resources, we will take a look into kernel optimization and other crucial OS settings. Finally, we will look into how to examine performance of MongoDB replication.

Advanced MySql Data-at-Rest Encryption in Percona Server

Presented by: Iwo Panowicz – Percona & Bart Oles – Severalnines AB

Session Details: The purpose of the talk is to present data-at-rest encryption implementation in Percona Server for MySQL.
Differences between Oracle’s MySQL and MariaDB implementation.

  • How it is implemented?
  • What is encrypted:
  • Tablespaces?
  • General tablespace?
  • Double write buffer/parallel double write buffer?
  • Temporary tablespaces? (KEY BLOCKS)
  • Binlogs?
  • Slow/general/error logs?
  • MyISAM? MyRocks? X?
  • Performance overhead.
  • Backups?
  • Transportable tablespaces. Transfer key.
  • Plugins
  • Keyrings in general
  • Key rotation?
  • General-Purpose Keyring Key-Management Functions
  • Keyring_file
  • Is useful? How to make it profitable?
  • Keyring Vault
  • How does it work?
  • How to make a transition from keyring_file

Polyglot Persistence Utilizing Open Source Databases as a Swiss Pocket Knife

Presented by: Art Van Scheppingen – vidaXL & Bart Oles – Severalnines AB

Session Details: Over the past few years, VidaXL has become a European market leader in the online retail of slow moving consumer goods. When a company achieved over 50% year over year growth for the past 9 years, there is hardly enough time to overhaul existing systems. This means existing systems will be stretched to the maximum of their capabilities, and often additional performance will be gained by utilizing a large variety of datastores. Polyglot persistence reigns in rapidly growing environments and the traditional one-size-fits-all strategy of monoglots is over. VidaXL has a broad landscape of datastores, ranging from traditional SQL data stores, like MySQL or PostgreSQL alongside more recent load balancing technologies such as ProxySQL, to document stores like MongoDB and search engines such as SOLR and Elasticsearch.
