The input data that is used to create this ML input channel.  
Type: [InputChannel](API_InputChannel.md) object  
Required: Yes

 ** [kmsKeyArn](#API_CreateMLInputChannel_RequestSyntax) **   <a name="API-CreateMLInputChannel-request-kmsKeyArn"></a>
The Amazon Resource Name (ARN) of the KMS key that is used to access the input channel.  
Type: String

Valid Range: Minimum value of 1. Maximum value of 30.  
Required: Yes

 ** [tags](#API_CreateMLInputChannel_RequestSyntax) **   <a name="API-CreateMLInputChannel-request-tags"></a>
The optional metadata that you apply to the resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.  
The following basic restrictions apply to tags:  
+ Maximum number of tags per resource - 50.
+ For each resource, each tag key must be unique, and each tag key can have only one value.
+ Maximum key length - 128 Unicode characters in UTF-8.
+ Maximum value length - 256 Unicode characters in UTF-8.
+ If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: \$1 - = . \$1 : / @.
+ Tag keys and values are case sensitive.
+ Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for keys as it is reserved for AWS use. You cannot edit or delete tag keys with this prefix. Values can have this prefix. If a tag value has aws as its prefix but the key does not, then Clean Rooms ML considers it to be a user tag and will count against the limit of 50 tags. Tags with only the key prefix of aws do not count against your tags per resource limit.
Type: String to string map  
Map Entries: Minimum number of 0 items. Maximum number of 200 items.  
Key Length Constraints: Minimum length of 1. Maximum length of 128.  
Value Length Constraints: Minimum length of 0. Maximum length of 256.  
Required: No
