MariaDB Galera Cluster
MariaDB Galera Cluster is a synchronous multi-primary clustering solution for MariaDB that lets every node in a cluster accept reads and writes while replicating committed transactions to all other nodes before they complete. It is built on the Galera write-set replication (wsrep) library originally developed by Codership, which MariaDB plc later acquired.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| three-node-galera | 3 | mariadb-galera-node |
| five-node-galera | 5 | mariadb-galera-node |
What drives the cost
- Dataset size (GB)
- Total dataset size across all databases. Drives InnoDB buffer pool sizing and storage capacity per node.
- Peak concurrent connections
- Peak simultaneous database connections across all application clients. Drives CPU thread pool sizing and memory allocation per connection.
