Lists the consumers registered to receive data from a stream using enhanced fan-out, and provides information about each consumer.
This operation has a limit of 5 transactions per second per stream.
Request Syntax{
"MaxResults": number,
"NextToken": "string",
"StreamARN": "string",
"StreamCreationTimestamp": number
}The request accepts the following data in JSON format.
The maximum number of consumers that you want a single call of ListStreamConsumers to return. The default value is 100. If you specify a value greater than 100, at most 100 results are returned.
Type: Integer
Valid Range: Minimum value of 1. Maximum value of 10000.
Required: No
When the number of consumers that are registered with the data stream is greater than the default value for the MaxResults parameter, or if you explicitly specify a value for MaxResults that is less than the number of consumers that are registered with the data stream, the response includes a pagination token named NextToken. You can specify this NextToken value in a subsequent call to ListStreamConsumers to list the next set of registered consumers.
Don't specify StreamName or StreamCreationTimestamp if you specify NextToken because the latter unambiguously identifies the stream.
You can optionally specify a value for the MaxResults parameter when you specify NextToken. If you specify a MaxResults value that is less than the number of consumers that the operation returns if you don't specify MaxResults, the response will contain a new NextToken value. You can use the new NextToken value in a subsequent call to the ListStreamConsumers operation to list the next set of consumers.
Tokens expire after 300 seconds. When you obtain a value for NextToken in the response to a call to ListStreamConsumers, you have 300 seconds to use that value. If you specify an expired token in a call to ListStreamConsumers, you get ExpiredNextTokenException.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1048576.
Required: No
The ARN of the Kinesis data stream for which you want to list the registered consumers. For more information, see Amazon Resource Names (ARNs) and AWS Service Namespaces.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 2048.
Pattern: arn:aws.*:kinesis:.*:\d{12}:stream/\S+
Required: Yes
Specify this input parameter to distinguish data streams that have the same name. For example, if you create a data stream and then delete it, and you later create another data stream with the same name, you can use this input parameter to specify which of the two streams you want to list the consumers for.
You can't specify this parameter if you specify the NextToken parameter.
Type: Timestamp
Required: No
{
"Consumers": [
{
"ConsumerARN": "string",
"ConsumerCreationTimestamp": number,
"ConsumerName": "string",
"ConsumerStatus": "string"
}
],
"NextToken": "string"
}If the action is successful, the service sends back an HTTP 200 response.
The following data is returned in JSON format by the service.
An array of JSON objects. Each object represents one registered consumer.
Type: Array of Consumer objects
When the number of consumers that are registered with the data stream is greater than the default value for the MaxResults parameter, or if you explicitly specify a value for MaxResults that is less than the number of registered consumers, the response includes a pagination token named NextToken. You can specify this NextToken value in a subsequent call to ListStreamConsumers to list the next set of registered consumers. For more information about the use of this pagination token when calling the ListStreamConsumers operation, see ListStreamConsumers:NextToken.
Tokens expire after 300 seconds. When you obtain a value for NextToken in the response to a call to ListStreamConsumers, you have 300 seconds to use that value. If you specify an expired token in a call to ListStreamConsumers, you get ExpiredNextTokenException.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 1048576.
For information about the errors that are common to all actions, see Common Errors.
The pagination token passed to the operation is expired.
