/AWS1/CL_ECA=>DECREASEREPLICACOUNT()

About DecreaseReplicaCount

Dynamically decreases the number of replicas in a Redis (cluster mode disabled) replication group or the number of replica nodes in one or more node groups (shards) of a Redis (cluster mode enabled) replication group. This operation is performed with no cluster down time.

Method Signature

IMPORTING

Required arguments:

IV_REPLICATIONGROUPID TYPE /AWS1/ECASTRING /AWS1/ECASTRING

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

IV_APPLYIMMEDIATELY TYPE /AWS1/ECABOOLEAN /AWS1/ECABOOLEAN

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

Optional arguments:

IV_NEWREPLICACOUNT TYPE /AWS1/ECAINTEGEROPTIONAL /AWS1/ECAINTEGEROPTIONAL

The number of read replica nodes you want at the completion of this operation. For Redis (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Redis (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:

• Redis (cluster mode disabled)

  • If Multi-AZ is enabled: 1

  • If Multi-AZ is not enabled: 0

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

IT_REPLICACONFIGURATION TYPE /AWS1/CL_ECACONFIGURESHARD=>TT_REPLICACONFIGURATIONLIST TT_REPLICACONFIGURATIONLIST

A list of ConfigureShard objects that can be used to configure each shard in a Redis (cluster mode enabled) replication group. The ConfigureShard has three members: NewReplicaCount, NodeGroupId, and PreferredAvailabilityZones.

IT_REPLICASTOREMOVE TYPE /AWS1/CL_ECAREMOVERPLSLIST_W=>TT_REMOVEREPLICASLIST TT_REMOVEREPLICASLIST

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