Struct DecreaseReplicaCountInput 

Source 
#[non_exhaustive]
pub struct DecreaseReplicaCountInput {
    pub replication_group_id: Option<String>,
    pub new_replica_count: Option<i32>,

Fields (Non-exhaustive)§

This struct is marked as 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 id of the replication group from which you want to remove replica nodes.

§new_replica_count: Option<i32>

The number of read replica nodes you want at the completion of this operation. For Valkey or Redis OSS (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Valkey or Redis OSS (cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group's node groups.

The minimum number of replicas in a shard or replication group is:

  • Valkey or Redis OSS (cluster mode disabled)

    • If Multi-AZ is enabled: 1

    • If Multi-AZ is not enabled: 0

  • Valkey or Redis OSS (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node fails)

§replica_configuration: Option<Vec<ConfigureShard>>

A list of ConfigureShard objects that can be used to configure each shard in a Valkey or Redis OSS replication group. The ConfigureShard has three members: NewReplicaCount, NodeGroupId, and PreferredAvailabilityZones.

§replicas_to_remove: Option<Vec<String>>

A list of the node ids to remove from the replication group or node group (shard).

§apply_immediately: Option<bool>

If True, the number of replica nodes is decreased immediately. ApplyImmediately=False is not currently supported.

Implementations§

The id of the replication group from which you want to remove replica nodes.

Source

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

The number of read replica nodes you want at the completion of this operation. For Valkey or Redis OSS (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Valkey or Redis OSS (cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group's node groups.

The minimum number of replicas in a shard or replication group is:

Source

pub fn replica_configuration(&self) -> &[ConfigureShard]

A list of ConfigureShard objects that can be used to configure each shard in a Valkey or Redis OSS replication group. The ConfigureShard has three members: NewReplicaCount, NodeGroupId, and PreferredAvailabilityZones.

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

Source

pub fn replicas_to_remove(&self) -> &[String]

A list of the node ids to remove from the replication group or node group (shard).

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

Source

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

If True, the number of replica nodes is decreased immediately. ApplyImmediately=False is not currently supported.
