Description

The ModifyReplicationGroup operation modifies the settings for a replication group.

Synopsis

Request

Request constructor

Request lenses

mrgApplyImmediately :: Lens' ModifyReplicationGroup (Maybe Bool) Source

If true, this parameter causes the modifications in this request and any pending modifications to be applied, asynchronously and as soon as possible, regardless of the PreferredMaintenanceWindow setting for the replication group.

If false, then changes to the nodes in the replication group are applied on the next maintenance reboot, or the next failure reboot, whichever occurs first.

Valid values: true | false

Default: false

mrgAutoMinorVersionUpgrade :: Lens' ModifyReplicationGroup (Maybe Bool) Source

Determines whether minor engine upgrades will be applied automatically to all of the clusters in the replication group during the maintenance window. A value of true allows these upgrades to occur; false disables automatic upgrades.

mrgAutomaticFailoverEnabled :: Lens' ModifyReplicationGroup (Maybe Bool) Source

Whether a read replica will be automatically promoted to read/write primary if the existing primary encounters a failure.

Valid values: true | false

mrgCacheParameterGroupName :: Lens' ModifyReplicationGroup (Maybe Text) Source

The name of the cache parameter group to apply to all of the clusters in this replication group. This change is asynchronously applied as soon as possible for parameters when the ApplyImmediately parameter is specified as true for this request.

mrgCacheSecurityGroupNames :: Lens' ModifyReplicationGroup [Text] Source

A list of cache security group names to authorize for the clusters in this replication group. This change is asynchronously applied as soon as possible.

This parameter can be used only with replication group containing cache clusters running outside of an Amazon Virtual Private Cloud (VPC).

Constraints: Must contain no more than 255 alphanumeric characters. Must not be Default.

mrgEngineVersion :: Lens' ModifyReplicationGroup (Maybe Text) Source

The upgraded version of the cache engine to be run on the cache clusters in the replication group.

mrgNotificationTopicArn :: Lens' ModifyReplicationGroup (Maybe Text) Source

The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.

mrgNotificationTopicStatus :: Lens' ModifyReplicationGroup (Maybe Text) Source

The status of the Amazon SNS notification topic for the replication group. Notifications are sent only if the status is active.

Valid values: active | inactive

mrgPreferredMaintenanceWindow :: Lens' ModifyReplicationGroup (Maybe Text) Source

The weekly time range (in UTC) during which replication group system maintenance can occur. Note that system maintenance may result in an outage. This change is made immediately. If you are moving this window to the current time, there must be at least 120 minutes between the current time and end of the window to ensure that pending changes are applied.

mrgPrimaryClusterId :: Lens' ModifyReplicationGroup (Maybe Text) Source

If this parameter is specified, ElastiCache will promote each of the cache clusters in the specified replication group to the primary role. The nodes of all other cache clusters in the replication group will be read replicas.

mrgReplicationGroupDescription :: Lens' ModifyReplicationGroup (Maybe Text) Source

A description for the replication group. Maximum length is 255 characters.

mrgReplicationGroupId :: Lens' ModifyReplicationGroup Text Source

The identifier of the replication group to modify.

mrgSecurityGroupIds :: Lens' ModifyReplicationGroup [Text] Source

Specifies the VPC Security Groups associated with the cache clusters in the replication group.

This parameter can be used only with replication group containing cache clusters running in an Amazon Virtual Private Cloud (VPC).

mrgSnapshotRetentionLimit :: Lens' ModifyReplicationGroup (Maybe Int) Source

The number of days for which ElastiCache will retain automatic node group snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted.

Important If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.

mrgSnapshotWindow :: Lens' ModifyReplicationGroup (Maybe Text) Source

The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of the node group specified by SnapshottingClusterId.

Example: '05:00-09:00'

If you do not specify this parameter, then ElastiCache will automatically choose an appropriate time range.

mrgSnapshottingClusterId :: Lens' ModifyReplicationGroup (Maybe Text) Source

The cache cluster ID that will be used as the daily snapshot source for the replication group.
