Response Elements

If the action is successful, the service sends back an HTTP 202 response.

The following data is returned in JSON format by the service.

BatchSize

The maximum number of items to retrieve in a single batch.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 10000.

BisectBatchOnFunctionError

(Streams only) If the function returns an error, split the batch in two and retry. The default value is false.

Type: Boolean

DestinationConfig

(Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.

Type: DestinationConfig object

EventSourceArn

The Amazon Resource Name (ARN) of the event source.

Type: String

Pattern: arn:(aws[a-zA-Z0-9-]*):([a-zA-Z0-9\-])+:([a-z]{2}(-gov)?-[a-z]+-\d{1})?:(\d{12})?:(.*)

FunctionArn

The ARN of the Lambda function.

Type: String

Pattern: arn:(aws[a-zA-Z-]*)?:lambda:[a-z]{2}(-gov)?-[a-z]+-\d{1}:\d{12}:function:[a-zA-Z0-9-_]+(:(\$LATEST|[a-zA-Z0-9-_]+))?

FunctionResponseTypes

(Streams only) A list of current response type enums applied to the event source mapping.

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 1 item.

Valid Values: ReportBatchItemFailures

LastModified

The date that the event source mapping was last updated or that its state changed, in Unix time seconds.

Type: Timestamp

LastProcessingResult

The result of the last Lambda invocation of your function.

Type: String

MaximumBatchingWindowInSeconds

(Streams and Amazon SQS standard queues) The maximum amount of time to gather records before invoking the function, in seconds. The default value is zero.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 300.

MaximumRecordAgeInSeconds

(Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.

Type: Integer

Valid Range: Minimum value of -1. Maximum value of 604800.

MaximumRetryAttempts

(Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.

Type: Integer

Valid Range: Minimum value of -1. Maximum value of 10000.

ParallelizationFactor

(Streams only) The number of batches to process concurrently from each shard. The default value is 1.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 10.

Queues

(Amazon MQ) The name of the Amazon MQ broker destination queue to consume.

Type: Array of strings

Array Members: Fixed number of 1 item.

Length Constraints: Minimum length of 1. Maximum length of 1000.

Pattern: [\s\S]*

SelfManagedEventSource

The self-managed Apache Kafka cluster for your event source.

Type: SelfManagedEventSource object

SourceAccessConfigurations

An array of the authentication protocol, VPC components, or virtual host to secure and define your event source.

Type: Array of SourceAccessConfiguration objects

Array Members: Minimum number of 0 items. Maximum number of 22 items.

StartingPosition

The position in a stream from which to start reading. Required for Amazon Kinesis, Amazon DynamoDB, and Amazon MSK stream sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams.

Type: String

Valid Values: TRIM_HORIZON | LATEST | AT_TIMESTAMP

StartingPositionTimestamp

With StartingPosition set to AT_TIMESTAMP, the time from which to start reading, in Unix time seconds.

Type: Timestamp

State

The state of the event source mapping. It can be one of the following: Creating, Enabling, Enabled, Disabling, Disabled, Updating, or Deleting.

Type: String

StateTransitionReason

Indicates whether a user or Lambda made the last change to the event source mapping.

Type: String

Topics

The name of the Kafka topic.

Type: Array of strings

Array Members: Fixed number of 1 item.

Length Constraints: Minimum length of 1. Maximum length of 249.

Pattern: ^[^.]([a-zA-Z0-9\-_.]+)

(Streams only) The duration in seconds of a processing window. The range is 1–900 seconds.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 900.

UUID
