Synopsis

Invokes the CreateStream operation against Amazon Kinesis.

Syntax

New-KINStream
-StreamName <String>
-ShardCount <Int32>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Creates an Amazon Kinesis stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream. You specify and control the number of shards that a stream is composed of. Each shard can support reads up to 5 transactions per second, up to a maximum data read total of 2 MB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MB per second. You can add shards to a stream if the amount of data input increases and you can remove shards if the amount of data input decreases. The stream name identifies the stream. The name is scoped to the AWS account used by the application. It is also scoped by region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different regions, can have the same name. CreateStream is an asynchronous operation. Upon receiving a CreateStream request, Amazon Kinesis immediately returns and sets the stream status to CREATING. After the stream is created, Amazon Kinesis sets the stream status to ACTIVE. You should perform read and write operations only on an ACTIVE stream. You receive a LimitExceededException when making a CreateStream request if you try to do one of the following:
  • Have more than five streams in the CREATING state at any point in time.
  • Create more shards than are authorized for your account.
For the default shard limit for an AWS account, see Streams Limits in the Amazon Kinesis Streams Developer Guide. If you need to increase this limit, contact AWS Support. You can use DescribeStream to check the stream status, which is returned in StreamStatus. CreateStream has a limit of 5 transactions per second per account.

Parameters

-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?False
-PassThru <SwitchParameter>
Returns the value passed to the StreamName parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False
-ShardCount <Int32>
The number of shards that the stream will use. The throughput of the stream is a function of the number of shards; more shards are required for greater provisioned throughput.DefaultShardLimit;
Required?False
Position?2
Accept pipeline input?False
-StreamName <String>
A name to identify the stream. The stream name is scoped to the AWS account used by the application that creates the stream. It is also scoped by region. That is, two streams in two different AWS accounts can have the same name, and two streams in the same AWS account but in two different regions can have the same name.
Required?False
Position?1
Accept pipeline input?True (ByValue, )

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? False
-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? False
-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? False
-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? False
-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? False
-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? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-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? False
-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? False

Inputs

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

Outputs

None or System.String
When you use the PassThru parameter, this cmdlet outputs the value supplied to the StreamName parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.Kinesis.Model.CreateStreamResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\>$streamName = New-KINStream -StreamName "mystream" -ShardCount 1 -PassThru
Creates a new stream. By default this cmdlet returns no output so the -PassThru switch is added to return the value supplied to the -StreamName parameter for subsequent use.
