Describes an individual setting that controls some aspect of ElastiCache behavior.

See: newParameter smart constructor.

Constructors

Parameter'

Fields

• allowedValues :: Maybe Text

  The valid range of values for the parameter.

• changeType :: Maybe ChangeType

  Indicates whether a change to the parameter is applied immediately or requires a reboot for the change to be applied. You can force a reboot or wait until the next maintenance window's reboot. For more information, see Rebooting a Cluster.

• dataType :: Maybe Text

  The valid data type for the parameter.

• description :: Maybe Text

  A description of the parameter.

• isModifiable :: Maybe Bool

  Indicates whether (true) or not (false) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

• minimumEngineVersion :: Maybe Text

  The earliest cache engine version to which the parameter can apply.

• parameterName :: Maybe Text

  The name of the parameter.

• parameterValue :: Maybe Text

  The value of the parameter.

• source :: Maybe Text

  The source of the parameter.

newParameter :: Parameter

Create a value of Parameter with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:allowedValues:Parameter', parameter_allowedValues - The valid range of values for the parameter.

$sel:changeType:Parameter', parameter_changeType - Indicates whether a change to the parameter is applied immediately or requires a reboot for the change to be applied. You can force a reboot or wait until the next maintenance window's reboot. For more information, see Rebooting a Cluster.

$sel:dataType:Parameter', parameter_dataType - The valid data type for the parameter.

$sel:description:Parameter', parameter_description - A description of the parameter.

$sel:isModifiable:Parameter', parameter_isModifiable - Indicates whether (true) or not (false) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

$sel:minimumEngineVersion:Parameter', parameter_minimumEngineVersion - The earliest cache engine version to which the parameter can apply.

$sel:parameterName:Parameter', parameter_parameterName - The name of the parameter.

$sel:parameterValue:Parameter', parameter_parameterValue - The value of the parameter.

$sel:source:Parameter', parameter_source - The source of the parameter.
