Overview

Instance::ClusterMap is a hash with cluster ID keys and cluster configuration values. It is used to create a cluster.

Examples:


clusters = Google::Cloud::Bigtable::Instance::ClusterMap.new

clusters.add("cluster-1", "us-east1-b", nodes: 3, storage_type: :SSD)

# Or
clusters.add("cluster-2", "us-east1-b")

Instance Method Details

#add(name, location, nodes: nil, storage_type: nil) ⇒ Object

Adds a cluster to the cluster map.

Parameters:

  • name (String) —

    The unique identifier for the cluster.

  • location (String) —

    The location where this cluster's nodes and storage reside. For best performance, clients should be located as close as possible to this cluster. Currently only zones are supported.

  • nodes (Integer) (defaults to: nil) —

    Number of nodes for the cluster. When creating an instance of type :DEVELOPMENT, nodes must not be set.

  • storage_type (Symbol) (defaults to: nil) —

    Valid values are:

    • :SSD(Flash (SSD) storage should be used), *:HDD(Magnetic drive (HDD) storage should be used)

    If not set then default will set to :STORAGE_TYPE_UNSPECIFIED
