2017/10/04 - Amazon Kinesis Analytics - 2 new 5 updated api methods
Changes Kinesis Analytics now supports schema discovery on objects in S3. Additionally, Kinesis Analytics now supports input data preprocessing through Lambda.
Adds an InputProcessingConfiguration to an application. An input processor preprocesses records on the input stream before the application's SQL code executes. Currently, the only input processor available is AWS Lambda .

Adds a streaming source to your Amazon Kinesis application. For conceptual information, see Configuring Application Input .
You can add a streaming source either when you create an application or you can use this operation to add a streaming source after you create an application. For more information, see CreateApplication .
Any configuration update, including adding a streaming source using this operation, results in a new version of the application. You can use the DescribeApplication operation to find the current application version.
This operation requires permissions to perform the kinesisanalytics:AddApplicationInput action.

Creates an Amazon Kinesis Analytics application. You can configure each application with one streaming source as input, application code to process the input, and up to five streaming destinations where you want Amazon Kinesis Analytics to write the output data from your application. For an overview, see How it Works .
In the input configuration, you map the streaming source to an in-application stream, which you can think of as a constantly updating table. In the mapping, you must provide a schema for the in-application stream and map each data column in the in-application stream to a data element in the streaming source.
Your application code is one or more SQL statements that read input data, transform it, and generate output. Your application code can create one or more SQL artifacts like SQL streams or pumps.
In the output configuration, you can configure the application to write data from in-application streams created in your applications to up to five streaming destinations.
To read data from your source stream or write data to destination streams, Amazon Kinesis Analytics needs your permissions. You grant these permissions by creating IAM roles. This operation requires permissions to perform the kinesisanalytics:CreateApplication action.
For introductory exercises to create an Amazon Kinesis Analytics application, see Getting Started .

list
Use this parameter to configure the application input.
You can configure your application to receive input from a single streaming source. In this configuration, you map this streaming source to an in-application stream that is created. Your application code can then query the in-application stream like a table (you can think of it as a constantly updating table).
For the streaming source, you provide its Amazon Resource Name (ARN) and format of data on the stream (for example, JSON, CSV, etc). You also must provide an IAM role that Amazon Kinesis Analytics can assume to read this stream on your behalf.
To create the in-application stream, you need to specify a schema to transform your data into a schematized version used in SQL. In the schema, you provide the necessary mapping of the data elements in the streaming source to record columns in the in-app stream.

Response {'ProcessedInputRecords': ['string']}
Infers a schema by evaluating sample records on the specified streaming source (Amazon Kinesis stream or Amazon Kinesis Firehose delivery stream). In the response, the operation returns the inferred schema and also the sample records that the operation used to infer the schema.
You can use the inferred schema when configuring a streaming source for your application. For conceptual information, see Configuring Application Input . Note that when you create an application using the Amazon Kinesis Analytics console, the console uses this operation to infer a schema and show it in the console user interface.
This operation requires permissions to perform the kinesisanalytics:DiscoverInputSchema action.
