Struct ModifyReplicationGroupShardConfigurationInput

#[non_exhaustive]
pub struct ModifyReplicationGroupShardConfigurationInput {
    pub replication_group_id: Option<String>,
    pub node_group_count: Option<i32>,
    pub apply_immediately: Option<bool>,

Represents the input for a ModifyReplicationGroupShardConfiguration operation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

replication_group_id: Option<String>

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

node_group_count: Option<i32>

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

apply_immediately: Option<bool>

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

Value: true

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).

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

Implementations

impl ModifyReplicationGroupShardConfigurationInput

pub fn replication_group_id(&self) -> Option<&str>

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

pub fn node_group_count(&self) -> Option<i32>

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

pub fn apply_immediately(&self) -> Option<bool>

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

Value: true

pub fn resharding_configuration(&self) -> &[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).

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .resharding_configuration.is_none().

pub fn node_groups_to_remove(&self) -> &[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 will attempt to remove all node groups listed by NodeGroupsToRemove from the cluster.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .node_groups_to_remove.is_none().

pub fn node_groups_to_retain(&self) -> &[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 will attempt to remove all node groups except those listed by NodeGroupsToRetain from the cluster.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .node_groups_to_retain.is_none().

impl ModifyReplicationGroupShardConfigurationInput

pub fn builder() -> ModifyReplicationGroupShardConfigurationInputBuilder

Creates a new builder-style object to manufacture ModifyReplicationGroupShardConfigurationInput.

Trait Implementations

impl Clone for ModifyReplicationGroupShardConfigurationInput

fn clone(&self) -> ModifyReplicationGroupShardConfigurationInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModifyReplicationGroupShardConfigurationInput

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

Formats the value using the given formatter.

impl PartialEq for ModifyReplicationGroupShardConfigurationInput

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

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

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

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