require 'fog/aws/parsers/redshift/cluster'
# ==== Parameters
#
# @param [Hash] options
# * :cluster_identifier - required - (String)
# A unique identifier for the cluster. You use this identifier to refer to the cluster
# for any subsequent cluster operations such as deleting or modifying. Must be unique
# for all clusters within an AWS account. Example: myexamplecluster
# * :allow_version_upgrade - (Boolean)
# If `true` , upgrades can be applied during the maintenance window to the Amazon
# Redshift engine that is running on the cluster. Default: `true`
# * :automated_snapshot_retention_period - (Integer)
# Number of days that automated snapshots are retained. If the value is 0, automated
# snapshots are disabled. Default: 1 Constraints: Must be a value from 0 to 35.
# * :cluster_parameter_group_name - (String)
# The name of the parameter group to be associated with this cluster. Default: The
# default Amazon Redshift cluster parameter group. Constraints: Must be 1 to 255
# alphanumeric characters or hyphens. First character must be a letter. Cannot end
# with a hyphen or contain two consecutive hyphens.
# * :cluster_security_groups - (Array<String>)
# A list of security groups to be associated with this cluster. Default: The default
# cluster security group for Amazon Redshift.
# * :cluster_type - (String)
# Type of the cluster. When cluster type is specified as single-node, the NumberOfNodes
# parameter is not required. multi-node, the NumberOfNodes parameter is required. Valid
# Values: multi-node | single-node Default: multi-node
# * :cluster_version - (String)
# The version of the Amazon Redshift engine software that you want to deploy on the
# cluster. The version selected runs on all the nodes in the cluster. Constraints:
# Only version 1.0 is currently available. Example: 1.0
# * :master_user_password - required - (String)
# The password associated with the master user account for the cluster that is being
# created. Constraints: Must be between 8 and 64 characters in length. Must contain at
# least one uppercase letter. Must contain at least one lowercase letter. Must contain
# one number.
# * :node_type - required - (String)
# The node type to be provisioned. Valid Values: dw.hs1.xlarge | dw.hs1.8xlarge.
# * :number_of_nodes - (Integer)
# The number of compute nodes in the cluster. This parameter is required when the
# ClusterType parameter is specified as multi-node. If you don't specify this parameter,
# you get a single-node cluster. When requesting a multi-node cluster, you must specify
# the number of nodes that you want in the cluster. Default: 1 Constraints: Value must
# be at least 1 and no more than 100.
# * :preferred_maintenance_window - (String)
# The weekly time range (in UTC) during which automated cluster maintenance can occur.
# Format: ddd:hh24:mi-ddd:hh24:mi Default: A 30-minute window selected at random from
# an 8-hour block of time per region, occurring on a random day of the week.
# Constraints: Minimum 30-minute window.
# * :vpc_security_group_ids - (Array<String>)
# A list of Virtual Private Cloud (VPC) security groups to be associated with the
# cluster. Default: The default VPC security group is associated with the cluster.
#
