ProxySQL Cluster
Here we’ll discuss some concepts about ProxySQL Cluster.
So What is Replication
Replication means there are multiple proxy server who are doing proxy with the traffic and all necessary configuration in all the nodes are same and in sync always. Change in any server configuration will eventually propagate to all other nodes and will behave the same. One can read or write in any server of the cluster. The following figure shows a cluster of four ProxySQL servers:
ProxySQL Cluster Features
- Virtually synchronous replication
- Read and write through any cluster node
- Cluster failover recovery
- Enhanced in performance than standalone proxy server
- Load balance in ProxySQL end
Next Steps
- Deploy ProxySQL Cluster using KubeDB.
