Creating a Cluster (V2) Function This API is used to create a cluster with multiple node types (for example, ess, ess-cold, ess-client, ess-master). Calling Method For details, see Calling APIs.

WithAk(ak). WithSk(sk). WithProjectId(projectId). Build() client := css.NewCssClient( css.CssClientBuilder(). WithRegion(region.ValueOf("<YOUR REGION>")). WithCredential(auth).
Changing Node Specifications (Discarded) Function This API is used to modify the node specifications of a cluster. It can only change the specifications of ess nodes (data nodes).
), digits, underscores (_), and hyphens (-).
Options: ess: data node ess-cold: cold data node ess-client: client node ess-master: master node Response Parameters Status code: 200 Request succeeded. None Example Requests Scale in a cluster by scaling in specified type of nodes.
However, if it is the other AZ, which contains two of the three master nodes, that fails, services will be interrupted, because fewer than half of the master nodes (or nodes that assume master node responsibilities) are available.

If the operation role is role, the value is one or multiple node types (such as ess, ess-master, ess-client, and ess-cold). Response Parameters Status code: 200 Request succeeded. None Example Requests Restart nodes of all or some types in the current cluster.
Restarting a Cluster (Deprecated) Function This API is used to restart a data node in a cluster, which will interrupt services. To restart all nodes in a cluster, you are advised to use [Restart Cluster V2] (RestartClusterMultiRole.xml).
Change Durations The following formulas can be used to estimate how long the node specifications change will take: Change duration (min) = 10 (min) x Total number of nodes to change + Data recovery duration (min) where, 10 minutes indicates how long non-data recovery operations (e.g
