Cluster Configuration Parameters
GridGain 9 cluster configuration is shared across the whole cluster. Regardless of which node you apply the configuration on, it will be propogated to all nodes in the cluster.
Checking Cluster Configuration
To get cluster configuration, use the CLI tool.
-
Start the CLI tool and connect to any node in the cluster.
-
Run the
cluster config showcommand.
The CLI tool will print the full cluster configuration. If you only need a part of the configuration, you can narrow down the search by providing the properties you need as the command argument, for example:
cluster config show transactionChanging Cluster Configuration
Cluster configuration is changed from the CLI tool. To change the configuration:
-
Start the CLI tool and connect to any node in the cluster.
-
Run the
cluster config updatecommand and provide the updated configuration as the command argument, for example:cluster config update metaStorage.idleSyncTimeInterval=600
The updated configuration will automatically be applied across the cluster,
Exporting Cluster Configuration
If you need to export cluster configuration to file, use the following command:
bin/gridgain9 cluster config show > cluster-config.txtConfiguration Parameters
