The opengauss database has two startup modes, namely independent mode and cluster mode.
-
Standalone mode:
- Standalone mode is suitable for single-node opengauss database instances.
- In standalone mode, the opengauss database is started as a single node, and the database process runs on one node.
- This mode is suitable for development, test environments, or small-scale deployments.
-
Cluster mode:
- Cluster mode is suitable for multi-node opengauss database instances.
- In cluster mode, the opengauss database is started in the form of a distributed cluster, and the database process runs in parallel on multiple nodes.
- Cluster mode can provide higher performance and scalability and is suitable for large-scale production environments.
In actual applications, the appropriate startup mode can be selected according to needs. If you only need a single-node database instance, you can choose standalone mode. If you need to build a high-availability, high-performance database cluster, you can choose cluster mode.
No matter which startup mode is chosen, it needs to be configured and deployed correctly according to the specific configuration and requirements to ensure the normal operation and efficient performance of the database.
