      • enabled

        public final Boolean enabled()

      • batchSize

        public final Integer batchSize()

        The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

        • Amazon DynamoDB Streams – Default 100. Max 10,000.

      • filterCriteria

        public final FilterCriteria filterCriteria()

        An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

        Returns:
        An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

      • maximumBatchingWindowInSeconds

        public final Integer maximumBatchingWindowInSeconds()

        The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

        For Kinesis, DynamoDB, and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

        Related setting: For Kinesis, DynamoDB, and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

        Returns:
        The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

        (Kinesis and DynamoDB Streams only) Discard records older than the specified age. The default value is infinite (-1).

        Returns:
        (Kinesis and DynamoDB Streams only) Discard records older than the specified age. The default value is infinite (-1).

      • bisectBatchOnFunctionError

        (Kinesis and DynamoDB Streams only) If the function returns an error, split the batch in two and retry.

        Returns:
        (Kinesis and DynamoDB Streams only) If the function returns an error, split the batch in two and retry.

      • maximumRetryAttempts

        public final Integer maximumRetryAttempts()

        (Kinesis and DynamoDB Streams only) 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.

      • hasSourceAccessConfigurations

        public final boolean hasSourceAccessConfigurations()
        For responses, this returns true if the service returned a value for the SourceAccessConfigurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • sourceAccessConfigurations

        public final List<SourceAccessConfiguration> sourceAccessConfigurations()

        An array of authentication protocols or VPC components required to secure your event source.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSourceAccessConfigurations() method.

        Returns:
        An array of authentication protocols or VPC components required to secure your event source.

      • tumblingWindowInSeconds

        public final Integer tumblingWindowInSeconds()

        (Kinesis and DynamoDB Streams only) The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

        Returns:
        (Kinesis and DynamoDB Streams only) The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

      • functionResponseTypes

        public final List<FunctionResponseType> functionResponseTypes()

        (Kinesis, DynamoDB Streams, and Amazon SQS) A list of current response type enums applied to the event source mapping.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFunctionResponseTypes() method.

        Returns:
        (Kinesis, DynamoDB Streams, and Amazon SQS) A list of current response type enums applied to the event source mapping.

      • hasFunctionResponseTypes

        public final boolean hasFunctionResponseTypes()
        For responses, this returns true if the service returned a value for the FunctionResponseTypes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • functionResponseTypesAsStrings

        public final List<String> functionResponseTypesAsStrings()

        (Kinesis, DynamoDB Streams, and Amazon SQS) A list of current response type enums applied to the event source mapping.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFunctionResponseTypes() method.

        Returns:
        (Kinesis, DynamoDB Streams, and Amazon SQS) A list of current response type enums applied to the event source mapping.

      • documentDBEventSourceConfig

        public final DocumentDBEventSourceConfig documentDBEventSourceConfig()

        Specific configuration settings for a DocumentDB event source.

        Returns:

      • kmsKeyArn

        public final String kmsKeyArn()

        The ARN of the Key Management Service (KMS) customer managed key that Lambda uses to encrypt your function's filter criteria. By default, Lambda does not encrypt your filter criteria object. Specify this property to encrypt data using your own customer managed key.

        Returns:
        The ARN of the Key Management Service (KMS) customer managed key that Lambda uses to encrypt your function's filter criteria. By default, Lambda does not encrypt your filter criteria object. Specify this property to encrypt data using your own customer managed key.
