Network.AWS.ElastiCache.ModifyReplicationGroupShardConfiguration

Performs horizontal scaling on a Redis (cluster mode enabled) cluster with no downtime. Requires Redis engine version 3.2.10 or newer. For information on upgrading your engine to a newer version, see Upgrading Engine Versions in the Amazon ElastiCache User Guide.

For more information on ElastiCache for Redis online horizontal scaling, see ElastiCache for Redis Horizontal Scaling

Creating a Request

modifyReplicationGroupShardConfiguration

Arguments

:: Text

mrgscReplicationGroupId

-> Int

mrgscNodeGroupCount

-> Bool

mrgscApplyImmediately

-> ModifyReplicationGroupShardConfiguration

Creates a value of ModifyReplicationGroupShardConfiguration with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• mrgscReshardingConfiguration - Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster's shards. If you omit this parameter ElastiCache selects availability zones for you. You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).
• mrgscNodeGroupsToRemove - If the value of NodeGroupCount is less than the current number of node groups (shards), NodeGroupsToRemove is a required list of node group ids to remove from the cluster.
• mrgscReplicationGroupId - The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.
• mrgscNodeGroupCount - The number of node groups (shards) that results from the modification of the shard configuration.
• mrgscApplyImmediately - Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true . Value: true

data ModifyReplicationGroupShardConfiguration

Represents the input for a ModifyReplicationGroupShardConfiguration operation.

Request Lenses

mrgscReshardingConfiguration :: Lens' ModifyReplicationGroupShardConfiguration [ReshardingConfiguration]

Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster's shards. If you omit this parameter ElastiCache selects availability zones for you. You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).

mrgscNodeGroupsToRemove :: Lens' ModifyReplicationGroupShardConfiguration [Text]

If the value of NodeGroupCount is less than the current number of node groups (shards), NodeGroupsToRemove is a required list of node group ids to remove from the cluster.

mrgscReplicationGroupId :: Lens' ModifyReplicationGroupShardConfiguration Text

The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.

mrgscNodeGroupCount :: Lens' ModifyReplicationGroupShardConfiguration Int

The number of node groups (shards) that results from the modification of the shard configuration.

mrgscApplyImmediately :: Lens' ModifyReplicationGroupShardConfiguration Bool

Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true . Value: true
