default java.lang.String |
getNodeGroupId()
Either the ElastiCache for Redis supplied 4-digit id or a user supplied id for the node group these configuration values apply to.
|
default java.lang.String |
getPrimaryAvailabilityZone()
The Availability Zone where the primary node of this node group (shard) is launched.
|
default java.util.List<java.lang.String> |
getReplicaAvailabilityZones()
A list of Availability Zones to be used for the read replicas.
|
default java.lang.Number |
getReplicaCount()
The number of read replica nodes in this node group (shard).
|
default java.lang.String |
getSlots()
A string of comma-separated values where the first set of values are the slot numbers (zero based), and the second set of values are the keyspaces for each slot.
|
default java.lang.String getNodeGroupId()
default java.lang.String getPrimaryAvailabilityZone()
default java.util.List<java.lang.String> getReplicaAvailabilityZones()
The number of Availability Zones in this list must match the value of ReplicaCount
or ReplicasPerNodeGroup
if not specified.
default java.lang.Number getReplicaCount()
default java.lang.String getSlots()
The following example specifies three slots (numbered 0, 1, and 2): 0,1,2,0-4999,5000-9999,10000-16,383
.
If you don't specify a value, ElastiCache allocates keys equally among each slot.
When you use an UseOnlineResharding
update policy to update the number of node groups without interruption, ElastiCache evenly distributes the keyspaces between the specified number of slots. This cannot be updated later. Therefore, after updating the number of node groups in this way, you should remove the value specified for the Slots
property of each NodeGroupConfiguration
from the stack template, as it no longer reflects the actual values in each node group. For more information, see UseOnlineResharding Policy .
