MariaDB/MySQL Auto-Сlustering with Embedded Load Balancing and Replication Types Selection

MariaDB/MySQL Auto-Clustering solution is packaged as an advanced highly available and auto-scalable cluster on top of managed Jelastic dockerized stack templates.

The package includes Highly Available ProxySQL Load Balancer and Cluster Orchestrator to manage MariaDB/MySQL replication topology. And there is a choice between different MariaDB/MySQL replication types:

Simple MariaDB/MySQL Replication

  • master-slave - provides a good consistency (i.e. exactly one node to modify data), but no automatic failover upon master failure. Slaves can be read without impact on master.
  • master-master - operates with two master nodes simultaneously, while other instances are configured as slaves.

MariaDB Galera Cluster

MariaDB Galera Cluster is a type of multi-master synchronous replication which is performed at a transaction commit time, by broadcasting transaction write set to all cluster nodes for applying with the following benefits:

  • No slave lag
  • No lost transactions
  • Both read and write scalability
  • Smaller client latencies

Cluster Horizontal Scaling

The topologies master-slave or master-master are improved with a new horizontal scaling algorithm. The key idea of that is a new cluster member is created via cloning an existing slave node. Right after the cloning procedure is completed the database on the new cluster member catches up data via binlog replay which definitely will be pretty short in time and guarantees the binlog will not expire unlike the case when the newly added node was created from scratch. Following this improvement we may guarantee cluster fast scaling with no inconsistencies that could arise since the binlog may be overwritten or expire during database cluster lifecycle before cloning.

Deployment to the Cloud

To get started, log in to Jelastic dashboard, import the required manifest using the link from GitHub: https://github.com/jelastic-jps/mysql-cluster/blob/master/manifest.jps

Or you can click the Deploy to Jelastic button, specify your email address within the widget, choose one of the Jelastic Public Cloud providers and press Install.

Deploy

Note: If you are already registered at Jelastic, you can deploy this cluster from Marketplace.

Installation Process

In the opened confirmation window at Jelastic dashboard, choose MariaDB/MySQL replication type with appropriate cluster topology, state the Environment name, optionally, customize its Display Name. If required you may exclude ProxySQL layer from the cluster topology before installation, just uncheck it. Keep in mind that you won’t be able to do that later and vice versa if you disable it before installation you will not be able to add the proxy layer afterward.Then, select the preferable region (if several are available) and click on Install.

After successful installation, you’ll receive a number of default emails based on your environment topology with access credentials.
