Galera introduction

Length: 4 min

Galera Cluster® Best Practices: DDL and Schema Upgrades

Length: 52

We will show how Galera Cluster executes DDLs in a safe, consistent manner across all the nodes in the cluster, and the differences with stand-alone MySQL. We will discuss how to prepare for and successfully carry out a schema upgrade and the considerations that need to be taken into account during the process.


Length: 47 MIN

In this part, we will discuss important topics related to multi-master setups:
* Practical considerations when using Galera in a multi-master setup
* Evaluating the characteristics of your database workload
* Preparing your application for multi-master
* Detecting and dealing with transaction conflicts

Galera Cluster Best Practices for DBAs and DevOps part 1

Length: 50 min

In the first part of Galera Cluster best practices series, we will discuss the following topics:

* ongoing monitoring of the cluster and detection of bottlenecks;
* fine-tuning the configuration based on the actual database workload;
* selecting the optimal State Snapshot Transfer (SST) method;
* backup strategies

Using Galera Replication to Create Geo-distributed Clusters on the WAN webinar video

Length: 55 min

We will show the advantages of having a geo-distributed database cluster and how to create one using Galera Cluster for MySQL. We will also discuss the configuration and status variables that are involved and how to deal with typical situations on the WAN such as slow, untrusted or unreliable links, latency and packet loss. We will demonstrate a multi-region cluster on Amazon EC2 and perform some throughput and latency measurements in real-time.

Migrating to Multi-Master Galera Cluster from Master-Slave MySQL Replication


This video provides the practical aspects of migrating a database setup based on traditional asynchronous replication to multi-master Galera Cluster. We will discuss the benefits Galera provides and how traditional replication settings, architecture and practices can be converted to Galera Cluster. We will show the steps that are needed to perform the migration with limited or no downtime, and will demonstrate the procedure in practice using a live database with an actual workload.

Galera Cluster Installation and Quick Start

Length: 1 hour

This video describes how to get started with Galera Cluster and build a functional multi-master cluster.

Once the nodes are up and running we will discuss how to monitor the health of the cluster and which status variables are important to watch.
