Response Structure
(dict) --
ProcessedClusters (list) --
The list of clusters that have been updated.
(dict) --
Contains all of the attributes of a specific cluster.
Name (string) --
The user-supplied name of the cluster. This identifier is a unique key that identifies a cluster.
Description (string) --
A description of the cluster
Status (string) --
The status of the cluster. For example, Available, Updating, Creating.
PendingUpdates (dict) --
A group of settings that are currently being applied.
Resharding (dict) --
The status of an online resharding operation.
SlotMigration (dict) --
The status of the online resharding slot migration
ProgressPercentage (float) --
The percentage of the slot migration that is complete.
ACLs (dict) --
A list of ACLs associated with the cluster that are being updated
ACLToApply (string) --
A list of ACLs pending to be applied.
ServiceUpdates (list) --
A list of service updates being applied to the cluster
(dict) --
Update action that has yet to be processed for the corresponding apply/stop request
ServiceUpdateName (string) --
The unique ID of the service update
Status (string) --
The status of the service update
NumberOfShards (integer) --
The number of shards in the cluster
Shards (list) --
A list of shards that are members of the cluster.
(dict) --
Represents a collection of nodes in a cluster. One node in the node group is the read/write primary node. All the other nodes are read-only Replica nodes.
Name (string) --
The name of the shard
Status (string) --
The current state of this replication group - creating, available, modifying, deleting.
Slots (string) --
The keyspace for this shard.
Nodes (list) --
A list containing information about individual nodes within the shard
(dict) --
Represents an individual node within a cluster. Each node runs its own instance of the cluster's protocol-compliant caching software.
Name (string) --
The node identifier. A node name is a numeric identifier (0001, 0002, etc.). The combination of cluster name, shard name and node name uniquely identifies every node used in a customer's Amazon account.
Status (string) --
The status of the service update on the node
AvailabilityZone (string) --
The Availability Zone in which the node resides
CreateTime (datetime) --
The date and time when the node was created.
Endpoint (dict) --
The hostname for connecting to this node.
Address (string) --
The DNS hostname of the node.
Port (integer) --
The port number that the engine is listening on.
NumberOfNodes (integer) --
The number of nodes in the shard
AvailabilityMode (string) --
Indicates if the cluster has a Multi-AZ configuration (multiaz) or not (singleaz).
ClusterEndpoint (dict) --
The cluster's configuration endpoint
Address (string) --
The DNS hostname of the node.
Port (integer) --
The port number that the engine is listening on.
NodeType (string) --
The cluster's node type
EngineVersion (string) --
The Redis engine version used by the cluster
EnginePatchVersion (string) --
The Redis engine patch version used by the cluster
ParameterGroupName (string) --
The name of the parameter group used by the cluster
ParameterGroupStatus (string) --
The status of the parameter group used by the cluster, for example 'active' or 'applying'.
SecurityGroups (list) --
A list of security groups used by the cluster
(dict) --
Represents a single security group and its status.
SecurityGroupId (string) --
The identifier of the security group.
Status (string) --
The status of the security group membership. The status changes whenever a security group is modified, or when the security groups assigned to a cluster are modified.
SubnetGroupName (string) --
The name of the subnet group used by the cluster
TLSEnabled (boolean) --
A flag to indicate if In-transit encryption is enabled
KmsKeyId (string) --
The ID of the KMS key used to encrypt the cluster
ARN (string) --
The Amazon Resource Name (ARN) of the cluster.
SnsTopicArn (string) --
The Amazon Resource Name (ARN) of the SNS notification topic
SnsTopicStatus (string) --
The SNS topic must be in Active status to receive notifications
SnapshotRetentionLimit (integer) --
The number of days for which MemoryDB retains automatic snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, a snapshot that was taken today is retained for 5 days before being deleted.
MaintenanceWindow (string) --
Specifies the weekly time range during which maintenance on the cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period.
SnapshotWindow (string) --
The daily time range (in UTC) during which MemoryDB begins taking a daily snapshot of your shard. Example: 05:00-09:00 If you do not specify this parameter, MemoryDB automatically chooses an appropriate time range.
ACLName (string) --
The name of the Access Control List associated with this cluster.
AutoMinorVersionUpgrade (boolean) --
When set to true, the cluster will automatically receive minor engine version upgrades after launch.
DataTiering (string) --
Enables data tiering. Data tiering is only supported for clusters using the r6gd node type. This parameter must be set when using r6gd nodes. For more information, see Data tiering.
UnprocessedClusters (list) --
The list of clusters where updates have not been applied.
(dict) --
A cluster whose updates have failed
ClusterName (string) --
The name of the cluster
ErrorType (string) --
