Properties

batchSize → int?

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

final

bisectBatchOnFunctionError → bool?

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

final

destinationConfig → DestinationConfig?

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

final

eventSourceArn → String?

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

final

functionArn → String?

The ARN of the Lambda function.

final

functionResponseTypes → List<FunctionResponseType>?

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

final

hashCode → int

The hash code for this object.

no setter, inherited

lastModified → DateTime?

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

final

lastProcessingResult → String?

The result of the last AWS Lambda invocation of your Lambda function.

final

maximumBatchingWindowInSeconds → int?

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

final

maximumRecordAgeInSeconds → int?

(Streams) Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

final

maximumRetryAttempts → int?

(Streams) Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

final

parallelizationFactor → int?

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

final

queues → List<String>?

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

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

selfManagedEventSource → SelfManagedEventSource?

The Self-Managed Apache Kafka cluster for your event source.

final

sourceAccessConfigurations → List<SourceAccessConfiguration>?

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

final

startingPosition → EventSourcePosition?

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

final

startingPositionTimestamp → DateTime?

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

final

state → String?

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

final

stateTransitionReason → String?

Indicates whether the last change to the event source mapping was made by a user, or by the Lambda service.

final

topics → List<String>?

The name of the Kafka topic.

final

tumblingWindowInSeconds → int?

(Streams) The duration of a processing window in seconds. The range is between 1 second up to 15 minutes.

final

uuid → String?

The identifier of the event source mapping.

final

Methods

noSuchMethod(Invocation invocation) → dynamic
