The AWS Lambda Developer Guide provides additional information. For the service overview, go to `What is AWS Lambda`_, and for information about how the service works, go to `AWS LambdaL How it Works`_ in the AWS Lambda Developer Guide. z 2014-11-11z us-east-1z lambda.us-east-1.amazonaws.com)� InvalidRequestContentException�ResourceNotFoundException� InvalidParameterValueException�ServiceExceptionc sP |� d�}|st| | j| j�}n|d= |j|d< tt| �jdi |�� || _d S )N�region�host� ) �getr �DefaultRegionName�DefaultRegionEndpoint�endpoint�superr �__init__r )�self�kwargsr �� __class__r �7/usr/lib/python3/dist-packages/boto/awslambda/layer1.pyr 7 s � z AWSLambdaConnection.__init__c C s dgS )Nzhmac-v4r )r r r r �_required_auth_capabilityB s z-AWSLambdaConnection._required_auth_capabilityNc C sT d}|||d�}i }i } |dur||d< |dur ||d< | j d|dt�|�|| d�S ) a� Identifies an Amazon Kinesis stream as the event source for an AWS Lambda function. AWS Lambda invokes the specified function when records are posted to the stream. This is the pull model, where AWS Lambda invokes the function. For more information, go to `AWS LambdaL How it Works`_ in the AWS Lambda Developer Guide. This association between an Amazon Kinesis stream and an AWS Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which AWS Lambda function to invoke) for the event source mapping in the request body. This operation requires permission for the `iam:PassRole` action for the IAM role. It also requires permission for the `lambda:AddEventSource` action. :type event_source: string :param event_source: The Amazon Resource Name (ARN) of the Amazon Kinesis stream that is the event source. Any record added to this stream causes AWS Lambda to invoke your Lambda function. AWS Lambda POSTs the Amazon Kinesis event, containing records, to your Lambda function as JSON. :type function_name: string :param function_name: The Lambda function to invoke when AWS Lambda detects an event on the stream. :type role: string :param role: The ARN of the IAM role (invocation role) that AWS Lambda can assume to read from the stream and invoke the function. :type batch_size: integer :param batch_size: The largest number of records that AWS Lambda will give to your function in a single event. The default is 100 records. :type parameters: map :param parameters: A map (key-value pairs) defining the configuration for AWS Lambda to use when reading the event source. Currently, AWS Lambda supports only the `InitialPositionInStream` key. The valid values are: "TRIM_HORIZON" and "LATEST". The default value is "TRIM_HORIZON". For more information, go to `ShardIteratorType`_ in the Amazon Kinesis Service API Reference. �"/2014-11-13/event-source-mappings/)� EventSource� FunctionName�RoleN� BatchSize� Parameters�POST�� ��expected_status�data�headers�params�� make_requestr �dumps) r � event_source� function_name�role� batch_size� parameters�urir' r& � query_paramsr r r �add_event_sourceE s 3� �z$AWSLambdaConnection.add_event_sourcec C � d� |�}| jd|dd�S )a Deletes the specified Lambda function code and configuration.

Upon receiving the request, Lambda executes the specified function asynchronously. To see the logs generated by the Lambda function execution, see the CloudWatch logs console.

For each mapping, the API returns configuration information (see AddEventSource). You can optionally specify filters to retrieve specific event source mappings.

You provide only the parameters you want to change. This operation must only be used on an existing Lambda function and cannot be used to update the function's code. This operation requires permission for the `lambda:UpdateFunctionConfiguration` action. :type function_name: string :param function_name: The name of the Lambda function. :type role: string :param role: The Amazon Resource Name (ARN) of the IAM role that Lambda will assume when it executes your function. :type handler: string :param handler: The function that Lambda calls to begin executing your function. For Node.js, it is the module-name.export value in your function. :type description: string :param description: A short user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit. :type timeout: integer :param timeout: The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds. :type memory_size: integer :param memory_size: The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB. rB Nr �Handler� Description�Timeout� MemorySize�PUTr" r# )r9 r) r r* ) r r, r- �handler� description�timeout� memory_sizer0 r' r& r1 r r r � update_function_configurationU s$ . �z1AWSLambdaConnection.update_function_configurationc C s d� |�} i } i } |dur|| d< |dur|| d< |dur!|| d< |dur)|| d< |dur1|| d< |dur9|| d< | durA| | d < ztt|��} W n* ttfys z|�� W n tttfyf td ��w tt� |� � �j �} Y nw | | d < | j d | d || | d�S )a Creates a new Lambda function or updates an existing function. The function metadata is created from the request parameters, and the code for the function is provided by a .zip file in the request body. If the function name already exists, the existing Lambda function is updated with the new code and metadata. This operation requires permission for the `lambda:UploadFunction` action. :type function_name: string :param function_name: The name you want to assign to the function you are uploading. The function names appear in the console and are returned in the ListFunctions API. Function names are used to specify functions to other AWS Lambda APIs, such as InvokeAsync. :type function_zip: blob :param function_zip: A .zip file containing your packaged source code. For more information about creating a .zip file, go to `AWS LambdaL How it Works`_ in the AWS Lambda Developer Guide. :type runtime: string :param runtime: The runtime environment for the Lambda function you are uploading.

For Node.js, it is the module-name . export value in your function. :type mode: string :param mode: How the Lambda function will be invoked. Lambda supports only the "event" mode. :type description: string :param description: A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit. :type timeout: integer :param timeout: The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time.
