.NET Framework 3.5
 
You can update an event source mapping. This is useful if you want to change the parameters of the existing mapping without losing your position in the stream. You can change which function will receive the stream records, but to change the stream itself, you must create a new mapping.

If you are using the versioning feature, you can update the event source mapping to map to a specific Lambda function version or alias as described in the FunctionName parameter. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

If you disable the event source mapping, AWS Lambda stops polling. If you enable again, it will resume polling from the time it had stopped polling, so you don't lose processing of any records. However, if you delete event source mapping and create it again, it will reset.

This operation requires permission for the lambda:UpdateEventSourceMapping action.
