Synopsis

Calls the Amazon ElastiCache ModifyReplicationGroupShardConfiguration API operation.

Syntax

Edit-ECReplicationGroupShardConfiguration
-ReplicationGroupId <String>
-ApplyImmediately <Boolean>
-NodeGroupCount <Int32>
-NodeGroupsToRemove <String[]>
-NodeGroupsToRetain <String[]>
-ReshardingConfiguration <ReshardingConfiguration[]>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Modifies a replication group's shards (node groups) by allowing you to add shards, remove shards, or rebalance the keyspaces among exisiting shards.

Parameters

-ApplyImmediately <Boolean>
Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true.Value: true
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NodeGroupCount <Int32>
The number of node groups (shards) that results from the modification of the shard configuration.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-NodeGroupsToRemove <String[]>
If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRemove is a list of NodeGroupIds to remove from the cluster.ElastiCache for Redis will attempt to remove all node groups listed by NodeGroupsToRemove from the cluster.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NodeGroupsToRetain <String[]>
If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRetain is a list of NodeGroupIds to retain in the cluster.ElastiCache for Redis will attempt to remove all node groups except those listed by NodeGroupsToRetain from the cluster.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the ReplicationGroupId parameter. The -PassThru parameter is deprecated, use -Select '^ReplicationGroupId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ReplicationGroupId <String>
The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-ReshardingConfiguration <ReshardingConfiguration[]>
Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster's shards. If you omit this parameter ElastiCache selects availability zones for you.You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'ReplicationGroup'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ElastiCache.Model.ModifyReplicationGroupShardConfigurationResponse). Specifying the name of a property of type Amazon.ElastiCache.Model.ModifyReplicationGroupShardConfigurationResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases AWSProfileName, StoredCredentials
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases SecretAccessKey, SK
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases ST
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)
Aliases RegionToCall
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? True (ByPropertyName)

Inputs

System.String
You can pipe a String object to this cmdlet for the ReplicationGroupId parameter.

Outputs

Amazon.ElastiCache.Model.ReplicationGroup or Amazon.ElastiCache.Model.ModifyReplicationGroupShardConfigurationResponse
This cmdlet returns an Amazon.ElastiCache.Model.ReplicationGroup object. The service call response (type Amazon.ElastiCache.Model.ModifyReplicationGroupShardConfigurationResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
