2022/08/17 - AWS Lambda - 5 updated api methods
Changes Added support for customization of Consumer Group ID for MSK and Kafka Event Source Mappings.
{'AmazonManagedKafkaEventSourceConfig': {'ConsumerGroupId': 'string'},
'SelfManagedKafkaEventSourceConfig': {'ConsumerGroupId': 'string'}}
Creates a mapping between an event source and an Lambda function. Lambda reads items from the event source and invokes the function.
For details about how to configure different event sources, see the following topics.
The following error handling options are available only for stream sources (DynamoDB and Kinesis):
BisectBatchOnFunctionError - If the function returns an error, split the batch in two and retry.
DestinationConfig - Send discarded records to an Amazon SQS queue or Amazon SNS topic.
MaximumRecordAgeInSeconds - 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
MaximumRetryAttempts - 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.
ParallelizationFactor - Process multiple batches from each shard concurrently.
For information about which configuration parameters apply to each event source, see the following topics.

SASL_SCRAM_512_AUTH - The Secrets Manager ARN of your secret key used for SASL SCRAM-512 authentication of your self-managed Apache Kafka brokers.
VIRTUAL_HOST - (Amazon MQ) The name of the virtual host in your RabbitMQ broker. Lambda uses this RabbitMQ host as the event source. This property cannot be specified in an UpdateEventSourceMapping API call.
CLIENT_CERTIFICATE_TLS_AUTH - (Amazon MSK, self-managed Apache Kafka) The Secrets Manager ARN of your secret key containing the certificate chain (X.509 PEM), private key (PKCS#8 PEM), and private key password (optional) used for mutual TLS authentication of your MSK/Apache Kafka brokers.
SERVER_ROOT_CA_CERTIFICATE - (Self-managed Apache Kafka) The Secrets Manager ARN of your secret key containing the root CA certificate (X.509 PEM) used for TLS encryption of your Apache Kafka brokers.
URI (string) --
The value for your chosen configuration in Type . For example: "URI": "arn:aws:secretsmanager:us-east-1:01234567890:secret:MyBrokerSecretName" .
SelfManagedEventSource (dict) --
The self-managed Apache Kafka cluster for your event source.
Endpoints (dict) --
The list of bootstrap servers for your Kafka brokers in the following format: "KAFKA_BOOTSTRAP_SERVERS": ["abc.xyz.com:xxxx","abc2.xyz.com:xxxx"] .

(string) --
MaximumRecordAgeInSeconds (integer) --
(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.
BisectBatchOnFunctionError (boolean) --
(Streams only) If the function returns an error, split the batch in two and retry. The default value is false.
MaximumRetryAttempts (integer) --
(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.
TumblingWindowInSeconds (integer) --
(Streams only) The duration in seconds of a processing window. The range is 1–900 seconds.
FunctionResponseTypes (list) --
(Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.
(string) --
AmazonManagedKafkaEventSourceConfig (dict) --
Specific configuration settings for an Amazon Managed Streaming for Apache Kafka (Amazon MSK) event source.
ConsumerGroupId (string) --
The identifier for the Kafka consumer group to join. The consumer group ID must be unique among all your Kafka event sources. After creating a Kafka event source mapping with the consumer group ID specified, you cannot update this value. For more information, see services-msk-consumer-group-id .
SelfManagedKafkaEventSourceConfig (dict) --
Specific configuration settings for a self-managed Apache Kafka event source.
ConsumerGroupId (string) --
The identifier for the Kafka consumer group to join. The consumer group ID must be unique among all your Kafka event sources. After creating a Kafka event source mapping with the consumer group ID specified, you cannot update this value. For more information, see services-msk-consumer-group-id .
