Top tips to drive your MariaDB Galera Cluster performance with new features

Length: 56

MariaDB Server has built in Galera Cluster since the 10.0 releases, and plenty of joint engineering happens between Codership and MariaDB Corporation and the MariaDB Foundation.

Galera Cluster as you may already know is a synchronous multi-primary (multi-master) replication solution, that has automatic node provisioning, with parallel replication, no secondary lag, with built-in automatic conflict detection and handling, plus components to allow load balancing.

So where does MariaDB Galera Cluster stand out compared to the rest? Here are a few selected features that may pique your interest:
* Galera 4 is standard in MariaDB Galera Cluster since MariaDB Server 10.4. Note that Galera Cluster is built-into MariaDB Server.
* The mysql database contains new tables: wsrep_cluster, wsrep_cluster_members, wsrep_streaming_log, and wsrep_allowlist.
* Streaming replication allows replicating transactions of an unlimited size, i.e. greater than 2GB.
* GTID handling with Galera Cluster and MariaDB Server are synchronised, thus you have seamless replication of MariaDB GTIDs to other nodes in the cluster.
* wsrep_mode to help you replicate MyISAM, and Aria storage engines.
* You can migrate from unencrypted replication to TLS Galera communications without any downtime.
* A JSON interface for wsrep node state, including progress logging for State Snapshot Transfers (SSTs). This also includes the IP allowlist for Galera Cluster nodes that can make the requests (currently a unique feature to MariaDB Server).
* Rolling upgrades from MariaDB Server 10.4 to later, are supported.

There are plenty more, considering there are **enterprise only features** like the Blackbox for Galera troubleshooting, encrypting of the gcache, and more. While we are at it, we will also cover the MariaDB MaxScale features that are Galera Cluster specific.

Length: 45

As with every Galera Manager release, we consider a huge amount of features, and we always improve the UI and functionality based on your feature requests, to ensure that as a user, you’re happier, but more importantly, more efficient in production.

One of the biggest feature requests was to have Percona XtraDB Cluster (PXC) be launched and managed from a Galera Manager, and we have delivered as such. Galera Manager is free, not only monitors your PXC nodes, but also deploys PXC for you, such that it is a fully-managed service. We do not require the complexity of Kubernetes to get deployed, either. And Galera Manager comes from the developers of Galera Cluster, Codership.

In this webinar we will cover:

* Create a 3-node Galera Cluster branch with Percona XtraDB Cluster (PXC), in Amazon Web Services (AWS) (it works on DigitalOcean too, as well as on premise, but the demonstration will focus on AWS)
* Deploy a 3-node Percona XtraDB Cluster (PXC) on your existing on-premise infrastructure
* Cost comparisons between what we offer and other managed services (including a comparison with Percona Monitoring and Management – PMM)
* Utilizing the over 600 monitoring metrics to effectively manage your Galera Cluster

We are going to be mostly live demo focused and will answer your questions as well.

Disaster recovery with Galera Cluster 2021 edition (3 datacenters with 9 Galera Cluster nodes demo)

Length: 60 mins

Disaster Recovery with Galera Cluster 2021 Edition video with 3 datacenter (Singapore, London, San Fransisco) 9 Galera Cluster nodes demo!

We talk a lot about Galera Cluster for MySQL being great for High Availability, but what about Disaster Recovery (DR)? Database outages may occur when you lose a data centre due to power outages or natural disaster, so why not plan appropriately in advance?

In this video, we will discuss the business considerations including achieving the highest possible uptime, focus on business impact, risk mitigation, and disaster recovery itself. What scenarios are right for you: fully synchronous replication across various data centres? A mix of synchronous and asynchronous to an offsite location?

We will discuss Galera Cluster, mixed setups, the use of proxies, and also evaluate some third party solutions. We will debunk claims about how Galera Cluster might not work across data centers, tell you how to successfully do this across data centres, with performance tuning settings for all the segments. Galera 4 has also been released, making the networking protocol a lot more robust, and the changes will be discussed.

This video will focus on architecture solutions, DR scenarios and how to ensure you are successful at the end of it all.
