Galera Cluster is a 2 days team training, designed for DBAs who need to setup a HA environment based on Galera technology: a synchronous, multimaster client. After this training, the attendee will be able to use MariaDB Cluster.
If you prefer, you may ask to focus the course on another Galera flavour: Percona Xtradb Cluster, or Galera Cluster for MySQL.
This training covers the necessary topics to setup new clusters and upgrade existing ones, monitor them, run ordinary administration and troubleshoot problems.
- Understanding Galera and WSREP
- Galera limitations and good practices
- Designing a cluster
- Starting a new cluster
- Transaction certification
- Galera Cache, SST, SSI
- Disaster recovery
- Avoiding flow control
- Performance tuning
- Causal reads
ALTER TABLE(TOI, RSU)
- Rolling upgrades
- Combining Galera and asynchronous replication
The course is designed for DBAs or DevOps with MariaDB working knowledge. A basic SQL knowledge is desirable.
All attendees should have a stable and reasonably fast internet connection. Having a backup connection to use in case of troubles is also desirable.
Attendees should have the following programs installed on their laptops:
- The latest MariaDB stable version, or another
version agreed with the customer before the beginning of the course. It
is recommended that we use the MariaDB version they will use in their
- mysql or mycli command-line interfaces. mysqli is bundled with MariaDB, whereas mycli is an open source project.
- A terminal that allows to run system commands.
The operating system of choice is not relevant, as long as it is not too old or too new to run the MariaDB version of choice.
Cost and timing
The Galera Cluster training has a cost of 2,500 GBP and its duration is 2 days.
A maximum of 15 attendees is allowed, and we encourage
customers to keep the number of attendees as low as 10. This allows a
good level of interactivity, and ensures that every attendee can obtain
the necessary support.
