Cluster configuration
On the Cluster Overview page for a Fluss cluster, you can view and modify the default cluster configurations. Only the cluster owner can modify these settings.
Procedure
Log in to the Realtime Compute for Apache Flink console.
On the Stream Storage (Fluss) tab, click Console in the Actions column to access the Fluss cluster.
The Cluster Configuration section on the Cluster Overview page lists the current settings. To modify a setting, click the edit icon to its right.
Parameters
Parameter | Description | Default |
Lake-stream integration status | Enables or disables the lake-stream integration service for the cluster. When this service is enabled, you can enable data lake synchronization for individual tables. For more information, see Access lake-stream integrated tables. | Disabled |
KV snapshot interval | Specifies the interval for creating snapshots of primary key tables. Snapshots are used for data disaster recovery. A shorter interval reduces potential data loss during recovery but increases storage and compute costs. | 10 minutes |
Minimum in-sync replicas | Specifies the minimum number of in-sync replicas that must acknowledge a write for it to be considered successful. A higher value improves data reliability but may increase write latency. This value cannot be greater than the default replica count. | 1 |
Default replica count | Specifies the default number of data replicas for each bucket in a new table. More replicas improve data availability but consume more storage resources. | 3 |
Default bucket count | Specifies the default number of buckets for a new table. The number of buckets determines the degree of data parallelism. For more information, see Data sharding. | 3 |
