2016/12/01 - AWS Lambda - 1 new 9 updated api methods
Changes Adds new API `getAccountSettings`, dotnetcore 1.0 runtime support, DeadLetterConfig, and event source mappings with kinesis streams.
Returns a customer's account settings.
You can use this operation to retrieve Lambda limit information such as code size and concurrency limits. For more information on limits, see AWS Lambda Limits . You can also retrieve resource usage statistics such as code storage usage and function count.

{'StartingPosition': ['AT_TIMESTAMP'], 'StartingPositionTimestamp': 'timestamp'}
Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.
This association between a stream source and a Lambda function is called the event source mapping.
Warning
This event source mapping is relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. For more information, go to AWS Lambda: How it Works in the AWS Lambda Developer Guide .
You provide mapping information (for example, which stream to read from and which Lambda function to invoke) in the request body.
Each event source, such as an Amazon Kinesis or a DynamoDB stream, can be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.
If you are using versioning, you can specify a specific function version or an alias via the function name parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases .
This operation requires permission for the lambda:CreateEventSourceMapping action.

Request Syntax
client.create_event_source_mapping(
EventSourceArn='string',
FunctionName='string',
Enabled=True|False,
BatchSize=123,
StartingPosition='TRIM_HORIZON'|'LATEST'|'AT_TIMESTAMP',
StartingPositionTimestamp=datetime(2015, 1, 1)
)
string
[REQUIRED]
The Amazon Resource Name (ARN) of the Amazon Kinesis or the Amazon DynamoDB stream that is the event source. Any record added to this stream could cause AWS Lambda to invoke your Lambda function, it depends on the BatchSize . AWS Lambda POSTs the Amazon Kinesis event, containing records, to your Lambda function as JSON.
string
[REQUIRED]
The Lambda function to invoke when AWS Lambda detects an event on the stream.
You can specify the function name (for example, Thumbnail ) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail ).
If you are using versioning, you can also provide a qualified function ARN (ARN that is qualified with function version or alias name as suffix). For more information about versioning, see AWS Lambda Function Versioning and Aliases
AWS Lambda also allows you to specify only the function name with the account ID qualifier (for example, account-id:Thumbnail ).
Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length.
boolean
Indicates whether AWS Lambda should begin polling the event source. By default, Enabled is true.
integer
The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. Your function receives an event with all the retrieved records. The default is 100 records.
string
[REQUIRED]
The position in the stream where AWS Lambda should start reading. Valid only for Kinesis streams. For more information, go to ShardIteratorType in the Amazon Kinesis API Reference .
datetime
The timestamp of the data record from which to start reading. Used with shard iterator type AT_TIMESTAMP. If a record with this exact timestamp does not exist, the iterator returned is for the next (later) record. If the timestamp is older than the current trim horizon, the iterator returned is for the oldest untrimmed data record (TRIM_HORIZON). Valid only for Kinesis streams.

Creates a new Lambda 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 operation will fail. Note that the function name is case-sensitive.
If you are using versioning, you can also publish a version of the Lambda function you are creating using the Publish parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases .
This operation requires permission for the lambda:CreateFunction action.

string
[REQUIRED]
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 Invoke .
string
[REQUIRED]
The runtime environment for the Lambda function you are uploading.
To use the Node.js runtime v4.3, set the value to "nodejs4.3". To use earlier runtime (v0.10.42), set the value to "nodejs".
Note
You can no longer create functions using the v0.10.42 runtime version as of November, 2016. Existing functions will be supported until early 2017 but we recommend you migrate them to nodejs4.3 runtime version as soon as possible.
string
[REQUIRED]
The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources. For more information, see AWS Lambda: How it Works .
string
[REQUIRED]
The function within your code that Lambda calls to begin execution. For Node.js, it is the module-name .*export* value in your function. For Java, it can be package.class-name::handler or package.class-name . For more information, see Lambda Function Handler (Java) .
dict
[REQUIRED]
The code for the Lambda function.
ZipFile (bytes) --
The contents of your zip file containing your deployment package. If you are using the web API directly, the contents of the zip file must be base64-encoded. If you are using the AWS SDKs or the AWS CLI, the SDKs or CLI will do the encoding for you. For more information about creating a .zip file, go to Execution Permissions in the AWS Lambda Developer Guide .
S3Bucket (string) --
Amazon S3 bucket name where the .zip file containing your deployment package is stored. This bucket must reside in the same AWS region where you are creating the Lambda function.

The Amazon S3 object (the deployment package) version you want to upload.
string
A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.
integer
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.
integer
The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU and memory 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.
boolean
This boolean parameter can be used to request AWS Lambda to create the Lambda function and publish a version as an atomic operation.

Note that the URL is valid for up to 10 minutes. The configuration information is the same information you provided as parameters when uploading the function.
Using the optional Qualifier parameter, you can specify a specific function version for which you want this information.

Updates the code for the specified Lambda function. This operation must only be used on an existing Lambda function and cannot be used to update the function configuration.
If you are using the versioning feature, note this API will always update the $LATEST version of your Lambda function. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases .
