Welcome to the first day of the Percona Live Open Source Database Conference: Percona Live 2017 tutorials day! While technically the first day of the conference, this day focused on provided hands-on tutorials for people interested in learning directly how to use open source tools and technologies.
Today attendees went to training sessions taught by open source database experts and got first-hand experience configuring, working with, and experimenting with various open source technologies and software.
The first full day (which includes opening keynote speakers and breakout sessions) starts Tuesday 4/25 at 9:00 am.
Some of the tutorial topics covered today were:
MySQL Performance Schema in Action
Sveta Smirnova, Alexander Rubin
Performance Schema in MySQL is becoming more mature from version to version. In version 5.7, it includes extended lock instrumentation, memory usage statistics, new tables for server variables, first time ever instrumentation for user variables, prepared statements and stored routines. In this tutorial Sveta and Alexander helped the participants try these new instruments out. They provided a test environment and a few typical problems that were hard to solve before MySQL 5.7.
Just a few examples: “Where is memory going?” , “Why do these queries hang?”, “How huge is the overhead of my stored procedures?”, “Why are queries waiting for metadata locks?”. Attendees learned how to collect and use this information.
Best Practices for MySQL High Availability in 2017
Colin Charles
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. Topics covered included but weren’t limited to MySQL replication, MHA, DRBD, Tungsten Replicator, Galera Cluster, NDB Cluster, Vitess, etc. The focus of the talk was what is recommended for today, and what to look out for.
InnoDB Architecture and Performance Optimization
Peter Zaitsev
InnoDB is the most commonly used storage engine for MySQL and Percona Server and is the focus for the majority of storage engine development by the MySQL and Percona Server teams. This tutorial looked at the InnoDB architecture, including new developments in MySQL 5.6 as well as Percona Server. It provided specific advice on server configuration, schema design, application architecture, and hardware choices.
MongoDB 101: What NoSQL is All About
Jon Tobin, Rick GolbaBarrett Chambers
MongoDB is quickly becoming one of the NoSQL standards, but represents a very different way of thinking from traditional RDBMSs. Many database users tend to think of things from the perspective of the transactional DBs that they know and love, but there are other ways of doing things. The Percona Solutions Engineering team helped attendees fill out their database resume and become a more knowledgeable user by showing them the basics. This tutorial gave users with little or no experience with NoSQL databases an introduction to MongoDB.
Join us tomorrow for the first full day of the Percona Live Open Source Database Conference 2017!
