CREATE CLUSTER syntax¶
CREATE CLUSTER name [cluster_option,...] cluster_option: 'value' as oath
Create a cluster.
By default, the cluster metadata is saved in the data_dir and can contain the metadata for a single cluster. Multiple clusters can be created on same instance, but the cluster metadata files can’t be shared in the same folder. Therefore, it’s required to define its own folder for each new cluster data using ‘path` option.
An optional list of nodes can be declared with ‘nodes’ option. Explicit definition of the nodes list may be required in cases where the nodes are located at different network segments or datacenters.
