delete-replication-group¶

Description¶

Deletes an existing replication group. By default, this operation deletes the entire replication group, including the primary/primaries and all of the read replicas. If the replication group has only one primary, you can optionally delete only the read replicas, while retaining the primary by setting RetainPrimaryCluster=true .

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

Note

This operation is valid for Redis only.

Synopsis¶

  delete-replication-group
--replication-group-id <value>
[--retain-primary-cluster | --no-retain-primary-cluster]
[--final-snapshot-identifier <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--replication-group-id (string)

The identifier for the cluster to be deleted. This parameter is not case sensitive.

--retain-primary-cluster | --no-retain-primary-cluster (boolean)

If set to true , all of the read replicas are deleted, but the primary node is retained.

--final-snapshot-identifier (string)

The name of a final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster, rather than one of the replicas; this is to ensure that it captures the freshest data. After the final snapshot is taken, the replication group is immediately deleted.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To delete a replication group

The following delete-replication-group example deletes an existing replication group. By default, this operation deletes the entire replication group, including the primary/primaries and all of the read replicas. If the replication group has only one primary, you can optionally delete only the read replicas, while retaining the primary by setting RetainPrimaryCluster=true .

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation. Valid for Redis only.

aws elasticache delete-replication-group \
    --replication-group-id "mygroup"

Output:

{
     "ReplicationGroup": {
         "ReplicationGroupId": "mygroup",
         "Description": "my group",
         "Status": "deleting",
         "PendingModifiedValues": {},
         "AutomaticFailover": "disabled",
