Operations and Management


Scenario: You work as a consultant and a new client has just signed on. Their DBA left suddenly leaving nothing but some outdated documentation in their wiki. After the kick-off meeting you realise that the operations and the development teams know little to none about the databases. They have been encountering intermittent problems with the application’s performance and suspect it’s related to the databases. You are told: "Please fix it ASAP!” So you have your public key installed on their jumphost and they manage to provide you with a 6 character long mysql root password. This is where your journey begins! During this session you will learn some of the best practices around discovering a new environment, finding possible threats and weaknesses and determining what key metrics to focus on for performance and reliability. We will cover architecture, replication, OS and MySQL level configuration, storage engines, failover strategies, backup and restores, monitoring, query tuning and possible ways to save money. The goal at the end of the presentation is to have a prioritized action plan. I will also explain the usage and the output of some tools/wrappers that help during an infrastructure review. Examples include creation of maximum integetr usage reports, table fragmentation and duplicate keys (we will be leveraging multiple Percona Toolkit scripts but also some lesser known tools as well). It is often easy to overlook underlying problems in the infrastructure during day-to-day operations, so this presentation will aim to highlight how to identify and resolve potenital bottlenecks with your systems.
