Content Breakdown

Note that Hands On Labs are denoted with HOL. All participants will be given remote VMs.

  • Install Galera Cluster with MySQL 5.7 and load data into it (while the course material will cover upgrading from MySQL 5.5 and 5.6, the HOL will start with MySQL 5.7)
  • Understand the changes in MySQL 8 and what might trip up your application (we will discuss character sets and collations, authentication changes, reserved words, SQL modes, data types, removed features, default changes, how minor version upgrades are one-way, and so on).
  • Understand the changes in Galera 4 and why MySQL 8 works better with it, thus improving your performance and reliability
  • The necessary checklist to successfully plan and execute a major upgrade, preferably with no downtime. We will discuss in-place upgrades, as well as migrating to newer hardware at the same time.
  • Configure a proxy (GLB, ProxySQL – HOL) if this is the chosen way
  • Test an upgrade (HOL)
  • Upgrade your Galera Cluster to MySQL 8 (HOL)
  • How and why does this differ from Percona XtraDB Cluster (PXC) and MariaDB Server? (HOL – homework; there will be an instructor-led demonstration). It is important to remember that Percona XtraDB Cluster (PXC) has enabled strict mode, traffic encryption, and more.
  • Can you upgrade from 5.5 to 8.0 directly, or must minor versions be upgraded? What about in the MariaDB Server world?
