Today we are pleased to announce the 1.4.1 release of ClusterControl – the all-inclusive database management system that lets you easily deploy, monitor, manage and scale highly available open source databases – and load balancers – in any environment: on-premise or in the cloud.
This release contains key new management features for MySQL and MariaDB load balancing with ProxySQL, along with performance improvements and bug fixes.
- Support for:
- MySQL Galera in addition to Replication clusters
- Active-standby HA setup with Keepalived
- Use the Query Monitor to view query digests
- Management features:
- Manage Query Rules (Query Caching, Query Rewrite)
- Manage Host Groups (Servers)
- Manage ProxySQL Database Users
- Manage ProxySQL System Variables
For Galera Cluster for MySQL & Replication
- Manage MySQL Galera and Replication clusters with management/public IPs
- For monitoring connections and data/private IPs for replication traffic
- Add MySQL Galera nodes or Replication Read Slaves with management and data IPs

Load balancers are an essential component in MySQL and MariaDB database high availability; especially when making topology changes transparent to applications and implementing read-write split functionality. As we all know, high-traffic database applications draw an enormous amount of queries daily. Which is why DBAs and SysAdmins require reliable technology solutions that can automatically scale to handle those connections while remaining available for still more.
And this is where load balancing technologies such as HAProxy, MaxScale and now ProxySQL come in.
ClusterControl has always come with support for HAProxy, as a generic TCP load balancer. We then added support for MariaDB’s MaxScale, an SQL-aware load balancer.
And today we’re happy to announce management support for ProxySQL, a lightweight yet complex protocol-aware proxy that sits between the MySQL clients and servers, in addition to the deployment and monitoring features for ProxySQL we announced two months ago.
Unlike others, ProxySQL understands MySQL protocol, which allows the implementation of features otherwise impossible to implement. For example, ProxySQL is the only proxy supporting connections multiplexing and query caching.
With that said, the new management features in ClusterControl include the following:
MySQL Galera in addition to Replication clusters
Up until now, ClusterControl enabled users to deploy ProxySQL on MySQL Replication clusters and monitor its performance. The same is now true for Galera Cluster for MySQL, MariaDB Galera Cluster and Percona XtraDB. This also includes active-standby HA setups with Keepalived.
Use the Query Monitor to view query digests
ClusterControl offers unified and comprehensive real-time monitoring of your entire database and server infrastructure. You can easily visualize performance in custom dashboards to establish operational baselines and support capacity planning. And with comprehensive reports for ProxySQL, you have a clear view of data points like connections, queries, data transfer and utilization, and more.
For more information on how monitoring works in ProxySQL, see our blog post on MySQL Load Balancing with ProxySQL – An Overview.
With ClusterControl, you can now easily configure and manage your ProxySQL deployments with its comprehensive UI. You can create servers, reorientate your setup, create users, set rules, manage query routing, and enable variable configurations. The new management features in ClusterControl for ProxySQL include:
Manage Query Rules (Query Caching, Query Rewrite)
- View running queries, create rules or cache and rewrite queries on the fly.
Manage Host Groups (Servers) – ProxySQL uses a concept of hostgroups – a group of different backends which serve the same purpose or handle similar type of traffic.
- Add or remove servers to existing and new host groups.
Manage ProxySQL Database Users
- Create new DB users or add existing MySQL users to ProxySQL.
Manage ProxySQL System Variables
- View and change global runtime variables for tweaking your ProxySQL instance.
For more information on how ProxySQL helps with MySQL query cache, query rewrite, and on ProxySQL’s host groups, read our blog on How ProxySQL adds Failover and Query Control to your MySQL Replication Setup.
There are a number of other features and improvements that we have not mentioned here. You can find all details in the ChangeLog.
We encourage you to test this latest release and provide us with your feedback. If you’d like a demo, feel free to request one.
Thank you for your ongoing support, and load balancing!
