Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.
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.
For .NET Core this operation is only available in asynchronous form. Please refer to UpdateEventSourceMappingAsync.

Exception | Condition |
---|---|
InvalidParameterValueException | One of the parameters in the request is not valid. |
ResourceConflictException | The resource already exists, or another operation is in progress. |

ResourceNotFoundException | The resource specified in the request does not exist. |
ServiceException | The Lambda service encountered an internal error. |
TooManyRequestsException | The request throughput limit was exceeded. For more information, see Lambda quotas. |
