# Change the parameters of the existing mapping without losing your position in the stream.
|
|
# http://docs.aws.amazon.com/lambda/latest/dg/API_UpdateEventSourceMapping.html
|
|
# ==== Parameters
|
|
# * UUID <~String> - event source mapping identifier.
|
|
# * BatchSize <~Integer> - maximum number of stream records that can be sent to your Lambda function for a single invocation.
|
|
# * Enabled <~Boolean> - specifies whether AWS Lambda should actively poll the stream or not.
|
|
# * FunctionName <~String> - Lambda function to which you want the stream records sent.
|
|
# ==== Returns
|
|
# * response<~Excon::Response>:
|
|
# * body<~Hash>:
|
|
# * 'BatchSize' <~Integer> - largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function.
|
|
# * 'EventSourceArn' <~String> - Amazon Resource Name (ARN) of the stream that is the source of events.
|
|
# * 'FunctionArn' <~String> - Lambda function to invoke when AWS Lambda detects an event on the stream.
|
|
# * 'LastModified' <~Time> - UTC time string indicating the last time the event mapping was updated.
|
|
# * 'LastProcessingResult' <~String> - result of the last AWS Lambda invocation of your Lambda function.
|
|
# * 'State' <~String> - state of the event source mapping.
|
|
# * 'StateTransitionReason' <~String> - reason the event source mapping is in its current state.
|
|
# * 'UUID' <~String> - AWS Lambda assigned opaque identifier for the mapping.
