* 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.
