2020/12/15 - AWS Lambda - 5 updated api methods
Changes Update lambda client to latest version

Creates a mapping between an event source and an AWS Lambda function. Lambda reads items from the event source and triggers the function.
For details about each event source type, see the following topics.
The following error handling options are only available 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.

Updates an event source mapping. You can change the function that AWS Lambda invokes, or pause invocation and resume later from the same location.
The following error handling options are only available 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.
