Struct ModifyReplicationGroupShardConfigurationMessage

pub struct ModifyReplicationGroupShardConfigurationMessage {
    pub apply_immediately: bool,
    pub node_group_count: i64,

}

Represents the input for a ModifyReplicationGroupShardConfiguration operation.

Fields

apply_immediately: bool

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

Value: true

node_group_count: i64

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

node_groups_to_remove: Option<Vec<String>>

If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRemove is a list of NodeGroupIds to remove from the cluster.

ElastiCache for Redis will attempt to remove all node groups listed by NodeGroupsToRemove from the cluster.

node_groups_to_retain: Option<Vec<String>>

If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRetain is a list of NodeGroupIds to retain in the cluster.

ElastiCache for Redis will attempt to remove all node groups except those listed by NodeGroupsToRetain from the cluster.

replication_group_id: String

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

resharding_configuration: Option<Vec<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).

Trait Implementations

impl Clone for ModifyReplicationGroupShardConfigurationMessage

fn clone(&self) -> ModifyReplicationGroupShardConfigurationMessage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModifyReplicationGroupShardConfigurationMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ModifyReplicationGroupShardConfigurationMessage

fn default() -> ModifyReplicationGroupShardConfigurationMessage

Returns the “default value” for a type.

impl PartialEq for ModifyReplicationGroupShardConfigurationMessage

fn eq(&self, other: &ModifyReplicationGroupShardConfigurationMessage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
